1 TI83, TI83 Plu or TI84 for NoBuie Statitic Chapter 3 Eterig Data Pre [STAT] the firt optio i already highlighted (:Edit) o you ca either pre [ENTER] or. Make ure the curor i i the lit, ot o the lit ame ad type the deired value preig [ENTER] after each oe. For xy data pair, eter all xvalue i oe lit. Eter all correpodig yvalue i a ecod lit. Pre [d] [QUIT] to retur to the home cree. To clear a previouly tored lit of data value, arrow up to the lit ame you wat to clear, pre [CLEAR], the pre eter. A alterative way i pre [STAT], pre 4 for 4:ClrLit, pre [d], the pre the umber key correpodig to the data lit you wih to clear, for example d will clear L. Pre [ENTER]. Oe Variable Statitic Pre [STAT]. Ue curor key to highlight CALC. Pre or [ENTER] to elect :Var Stat. Pre [d], the pre the umber key correpodig to your data lit. Pre Eter to calculate the tatitic. Note: the calculator alway default to L if you do ot pecify a data lit. Note: Sx i the ample tadard deviatio. The quartile calculated by the TI calculator differ omewhat from thoe foud uig the procedure i the text for thi cla. Make ure that you do the quartile by had. Sortig Data Pre [STAT]. Pre or [ENTER] to elect SortA(. Pre [d], the pre the umber key correpodig to your data lit that you wat to ort. Pre Eter, the calculator ay Doe. To ee the orted data go back ito the Edit mode. Chapter 4 Factorial O the home cree, eter the umber of which you would like to fid the factorial. Pre [MATH]. Ue curor key to move to the PRB meu. Pre 4 (4:!) Pre [ENTER] to calculate. Combiatio/Permutatio Eter the umber trial () o the home cree. Pre [MATH]. Ue curor key to move to the PRB meu. Pre for permutatio (: P r ), 3 for combiatio (3: C r ). Eter the umber of uccee (r). Pre [ENTER] to calculate. Chapter 5 Mea, Variace ad Stadard Deviatio of a Dicrete Probability Ditributio Table Pre [STAT] the firt optio i already highlighted (:Edit) o you ca either pre [ENTER] or. Make ure the curor i i the lit, ot o the lit ame ad type the deired value preig [ENTER] after each oe. For X ad P(X) data pair, eter all Xvalue i oe lit. Eter all correpodig P(X)value i a ecod lit. Pre [STAT]. Ue curor key to highlight CALC. Pre or [ENTER] to elect :Var Stat. Pre [d], the pre the umber key correpodig to your X lit, the a comma, the [d] ad the umber key correpodig to your P(X) value. (Should look like thi Var Stat L,L ) Pre Eter to calculate the tatitic. Where the calculator ay x thi i µ the populatio mea ad σx i the populatio tadard deviatio (quare thi umber to get the populatio variace). Biomial Ditributio Pre [d] [DISTR]. Thi will get you a meu of probability ditributio. Pre 0 or arrow dow to 0:biompdf( ad pre [ENTER]. Thi put biompdf( o the home cree. Eter the value for, p ad x with a comma betwee each. Pre [ENTER]. Thi i the probability deity fuctio ad will retur you the probability of exactly x uccee. If you leave off the x value ad jut eter ad p, you will get all the probabilitie for each x from 0 to. Pre [ALPHA] A or arrow dow to A:biomcdf( ad pre [ENTER]. Thi put biomcdf( o the home cree. Eter the value for, p ad x with a comma betwee each. Pre [ENTER]. Thi i the cumulative ditributio fuctio ad will retur you the probability of at mot x uccee. Poio Ditributio Pre [d] [DISTR]. Thi will get you a meu of probability ditributio.
2 Pre [ALPHA] B or arrow dow to B:poiopdf( ad pre [ENTER]. Thi put poiopdf( o the home cree. Eter the value for ad x with a comma betwee each. Pre [ENTER]. Thi i the probability deity fuctio ad will retur you the probability of exactly x uccee. Pre [ALPHA] C or arrow dow to C:poiocdf( ad pre [ENTER]. Thi put poiocdf( o the home cree. Eter the value for ad x with a comma betwee each. Pre [ENTER]. Thi i the cumulative ditributio fuctio ad will retur you the probability of at mot x uccee. Note: the calculator doe ot have the multiomial ad hypergeometric ditributio. Chapter 6 Normal Ditributio Pre [d] [DISTR]. Thi will get you a meu of probability ditributio. Pre or arrow dow to :ormalcdf( ad pre [ENTER]. Thi put ormalcdf( o the home cree. Eter the value for the lower x value (x ), upper x value (x ),, ad with a comma betwee each. Pre [ENTER]. Thi i the cumulative ditributio fuctio ad will retur P(x <x<x ). For example to fid P(80< X < 0) whe the mea i 00 ad the tadard deviatio i 0, you hould have ormalcdf(80,0,00,0) If you leave out the ad, the the default i the tadard ormal ditributio. For a left tail area ue a lower boud of E99 (egative ifiity), (pre [d] [EE] to get E) ad for a right tail are ue a upper boud of E99 (ifiity). For example to fid P(Z < .37) you hould have ormalcdf(e99,.37) Ivere Normal Ditributio Pre [d] [DISTR]. Thi will get you a meu of probability ditributio. Pre 3 or arrow dow to 3:ivNorm( ad pre [ENTER]. Thi put ivnorm( o the home cree. Eter the area to the left of the x value,, ad with a comma betwee each. Pre [ENTER]. Thi will retur the percetile for the x value. For example to fid the 95 th percetile whe the mea i 00 ad the tadard deviatio i 0, you hould have ivnorm(.95,00,0). If you leave out the ad, the the default i the zcore for the tadard ormal ditributio. Chapter 7 Cofidece Iterval for oe ample The 00(  )% cofidece iterval for, i kow, i X z a /.
