D) median equals the standard deviation. 18) A study was recently done in which 500 people were asked to indicate their preferences for one of three products. The following table shows the breakdown of the responses by gender of the respondents. Product Preference Gender A B C Male Female Based on these data, the probability that a person in the population will prefer product A can be assessed as: A) 0.56 B) 0.18 C) D) ) A lab orders 100 rats a week for each of the 52 weeks in the year for experiments that the lab conducts. Prices for 100 rats follow the following distribution: Price: $10.00 $12.50 $15.00 Probability: How much should the lab budget for next yearʹs rat orders be, assuming this distribution does not change? A) $650 B) $520 C) $637 D) $780 20) A package delivery service claims that no more than 5 percent of all packages arrive at the address late.
