1 SPSS/Excel Workshop 2 Semester One, 2010 In Assignment 2 of STATS 10x you may want to use Excel or SPSS to perform some calculations, that is, finding Normal probabilities and Inverse Normal values in Question 3. You may also like to use Excel and SPSS to check you ve done your by hand calculations correctly for your confidence intervals in Questions 5 and 6. Instructions from your assignment sheet read: Question guide Question 3 will require use of Excel, SPSS or a graphics calculator for calculating probabilities from Normal distributions. Do not hand in any computer output for these questions. Use Excel, SPSS or a graphics calculator to find the solutions. DO NOT USE TABLES. Question 3. [9 marks] [Chapter 6] Reminder: When calculating Normal probabilities, use SPSS, Excel or a graphics calculator. Do not use tables. Report any probabilities to 4 decimal places. On the following pages are some questions from the Worked Examples document which you can find on Cecil. Question 6 [Chapter 6] (helpful for Question 3, Assignment 2) A medical trial was conducted to investigate whether a new drug extended the life of a patient who had lung cancer. The survival times (in months) for 38 cancer patients who were treated with the drug are as follows: 1, 1, 5, 9, 10, 13, 14, 17, 18, 18, 19, 21, 22, 25, 25, 25, 26, 27, 29, 36, 38, 39, 39, 40, 41, 41, 43, 44, 44, 45, 46, 46, 49, 50, 50, 54, 54, 59. Sample mean 31.1 months and sample standard deviation 16.0 months. Assume that the survival time (in months) for patients on this drug is Normally distributed with a mean of 31.1 months and a standard deviation of 16.0 months. (i) What is the probability that a patient survives for no more than one year? (ii) What percentage of patients survive for at least two years? (iii) What proportion of patients will survive between one year and two years? (iv) What is the highest survival time that 80% of patient survival times exceed? (v) What is the lower quartile of the survival times? (vi) Calculate the central 80% of survival times. Student Learning Centre 1

2 Question 6 Solutions Let X be the survival time ( ) for a patient on the drug. X ~ Normal (µ =, σ = ) (i) Pr( X ) = (4dp) µ= (ii) Pr( X ) = µ= = = (2dp) (iii) Pr( ) = Pr( ) Pr( ) µ= = = (4dp) (iv) We want to calculate x such that Pr( X x ) = Pr( X x ) = x = (1dp) µ= The highest survival time that 80% of patient survival times exceed is months. Student Learning Centre 2

3 (v) We want to calculate x such that Pr(X x) = x = (1dp) µ= The lower quartile of the survival times is months. (vi) For the central 80% of survival times: Pr(x L X x U ) = 0.80 Pr(X x L ) = x L = (1dp) µ= Pr(x L X x U ) = 0.80 Pr(X x U ) = x U = (1dp) The central 80% of survival times fall between months and months. Excel Calculating Normal Probabilities A. Lower tail probabilities: Pr(X x) Example: Find Pr(X 5) where X ~ Normal(µ = 7, σ = 6) 1. Click in cell A1. 2. Click the Insert Function button from beside the formula bar. 3. Choose Statistical from the Or select a category box in the Insert Function dialog box. Student Learning Centre 3

4 4. Choose NORMDIST from the Select a function box (Figure 1). 5. Click OK. Figure 1 6. Fill in the NORMDIST dialog box (Figure 2). where: Figure 2 X Mean is the value for which we want the distribution. It is equivalent to x in our manual. In this example, we put 5 in this box. is the mean of the distribution. It is equivalent to µ in our manual. In this example, we put 7 in this box. Student Learning Centre 4

5 Standard_dev Cumulative is the standard deviation of the distribution. It is equivalent to σ in our manual. In this example, we put 6 in this box. indicates whether we want a cumulative distribution function (TRUE or 1) or a probability mass function (FALSE or 0). We will always put TRUE or 1 in this box. 7. Click OK. (The value of should appear in cell A1.) B. Upper tail probabilities: Pr(X x) Example: Find Pr(X 9) where X ~ Normal(µ = 7, σ = 6) Note: Pr(X 9) = 1 Pr(X 9) 1. Evaluate Pr(X 9) in cell B1 (use steps in A). 2. In cell B2, type: =1 B1. 3. Press Enter. (The value of should appear in cell B2.) C. Pr(a X b) Example: Find Pr(5 X 11) where X ~ Normal(µ = 7, σ = 6) Note: Pr(5 X 11) = Pr(X 11) Pr(X 5) 1. Evaluate Pr(X 11) in cell C1 (use steps in A). 2. Evaluate Pr(X 5) in cell C2 (use steps in A). 3. In cell C3, type: =C1 C2. 4. Press Enter. (The value of should appear in cell C3.) Student Learning Centre 5

6 Note: Another way to calculate Normal probabilities is to type the function =NORMDIST(x, µ, σ, c) directly into a cell, where: x is the value for which we want the distribution. µ is the mean of the distribution. σ is the standard deviation of the distribution c is always 1. For example: To evaluate Pr(X 5): In cell A1, type: =NORMDIST(5, 7, 6, 1). To evaluate Pr(X 9): In cell B1, type: =NORMDIST(9, 7, 6, 1) In cell B2, type: =1 B1. To evaluate Pr(5 X 11): In cell C1, type: =NORMDIST(11, 7, 6, 1). In cell C2, type: =NORMDIST(5, 7, 6, 1). In cell C3, type: =C1 C2. Figure 3 Student Learning Centre 6

7 Calculating the Inverse of the Normal Distribution Sometimes the x-value for a specified probability is required. Example: What mark would a student have to get more than, in order to be in the top 25% of the class, if the mean mark was 65 out of 100 and the standard deviation was 9? 1. Click in cell A1. 2. Click the Insert Function button from beside the formula bar. 3. Choose Statistical from the Function category list box in the Paste Function dialog box. 4. Choose NORMINV from the Function name list box (Figure 4). Figure 4 5. Click OK. 6. Fill in the NORMINV dialog box (Figure 5). Student Learning Centre 7

8 Figure 5 Note: the Excel function NORMINV determines the x-value for the probability that is to the left of the required x-value. In this example we want the top 25% therefore we use , or 0.75 for the probability. If instead we wanted the bottom 25% the probability is Click OK. (The value of should appear in cell A1.) Note: The formula can be directly entered into the cell by typing =NORMINV(p, µ, σ), where: p is the probability to the left of the x-value being calculated µ is the mean of the distribution σ is the standard deviation of the distribution Note: Excel has two other functions that work in the same manner as the functions explained above. These two functions are NORMSDIST and NORMSINV. These two functions calculate the value for a standard normal distribution, ie. X ~ Normal(0, 1). Student Learning Centre 8

9 Calculating the t-multiplier (Calculating the Inverse of the Student t-distribution) Example: Find the t-multiplier for a 95% confidence interval with degrees of freedom, df = 29. (That is: t 29 (0.025), probability and 29 degrees of freedom). 1. Click in cell A1. 2. Click the Insert Function button from beside the formula bar. 3. Choose Statistical from the Or select a category box in the Insert Function dialog box. 4. Choose TINV from the Select a function box (Figure 4). Figure 4 Student Learning Centre 9

10 5. Click OK 6. Fill in the TINV dialog box (Figure 5). Figure 5 Note: The Excel function TINV calculates the t-value for two tailed t-distribution. So if we want to find the t-value whose probability to the right is 0.1, then in the TINV function the value for the probability is entered as 0.2, because of the two-tailed nature of the function. 7. Click OK. (The value should appear in cell A1.) Note: The example can be solved by directly typing the formula =TINV(p, df) into the cell, where: p is the probability for the two-tailed distribution df is the number of degrees of freedom for the distribution Student Learning Centre 10

13 Question 10 [Chapter 8] (similar to Question 6, Assignment 2) In April 1996 the New Zealand Consumers' Institute conducted a survey on home computer use subscribers to Consumer Magazine were randomly selected and sent a survey form. Of those surveyed, 2730 had a computer for personal use at home. The respondents who had a home computer were given a list of computer activities and were asked to indicate all of those that they engaged in. They were also asked to indicate the number of hours per week that they used their computer. The Consumers' Institute used the results to draw conclusions about subscribers who own a home computer. The results of the survey are given in the two tables below. Computer Activities Computer Use (hours per week) Word-processing 2621 Not used 27 Games 1502 Used for less than 2 hours 328 Spreadsheets 819 Over 2 and up to 7 hours (incl) 764 Accounting 655 Over 7 and up to 14 hours (incl) 710 Databases 437 Over 14 and up to 21 hours (incl) 546 Internet 328 Over 21 and up to 28 hours (incl) 109 Drawing 300 Over 28 and up to 35 hours (incl) 136 Desktop publishing 246 Over 35 and up to 44 hours (incl) 55 Fax / answering machine 82 Over 44 hours 55 Total 2730 (c) Identify the sampling situation as (a) Two independent samples, (b) Single sample, several response categories or (c) Single sample, two or more Yes/No items in the following cases: (i) Consider the results from the New Zealand Consumers' Institute survey on home computer use above. We want to compare the proportion of respondents who use their home computer for spreadsheets with the proportion of respondents who use their home computer for accounting. (ii) Consider the results from the New Zealand Consumers' Institute survey on home computer use above. We want to compare the proportion of respondents who use their home computer for over 7 and up to 14 hours per week and the proportion of respondents who use their home computer for over 14 and up to 21 hours per week. Student Learning Centre 13

14 (iii) As part of a nationwide telephone survey in 1998, data was collected on people who use their home computers for Internet activities. We want to compare the proportion of respondents (in this survey) who use their home computer for the Internet to the proportion of respondents from the Consumers' Institute survey who use their home computer for the Internet. (d) By hand, calculate a 95% confidence interval for the difference between the proportion of people who use their computer for drawing and the proportion of people who use their computer for desktop publishing. Interpret your results. 1 Parameter = p D p P, the difference in the true proportion of people with a home computer who use it for drawing and the true proportion who use it for desktop publishing. 2 Estimate = pˆ D pˆ P, the difference in the proportion of respondents with a home computer who use it for drawing and the proportion who use it for desktop publishing = p ˆ D pˆ P = = = Formula = estimate ± t se(estimate) gives pˆ pˆ ) ± t se(ˆ p pˆ ) ( D P D P 4 Situation (c): One sample, two or more Yes/No items. p ˆ pˆ = = 0.2, q ˆ qˆ = = 1. 8 D se(ˆ p + P D pˆ ) = P df = (working with proportions) 2 D + P = For a 95% confidence interval with df =, use t = z = % confidence interval is: pˆ pˆ ) ± z se(ˆ p pˆ ) = ± = ± = (0.0030, ) ( D P D P 8 With 95% confidence, we estimate that the true proportion of people with a home computer who use it for drawing to be up to 0.04 higher than the true proportion who use it for desktop publishing.
