Question

As with the homework on confidence intervals, you will use JMP to anze the Deflategate data set. This time you will analyze the data using hypothesis tests. As a reminder, each student is randomly assigned one of 10 versions of this dataset. This time, your version is 7 It is recommended that you read the .pdf document outlining what is in this dataset before you begin. You can find this document on Canvas under "Additional Class Stuff/Data 1. Report the values of the following (this question is identical to question 1 from the last homework, however your data version may be different) a. Mean halftime PSI for Colts 12.68 b. Standard deviation of mean halftime PSI for Colts 1039 c. Standard error of mean halftime PSI for Colts-05196 d, 95% CI foryeCol e, Mean halftime PSI for Patriots 11.16 f. Standard deviation of mean halftime PSI for Patriots421 g. Standard error of mean halftime PSI for Patriots = .1269 h. 95% CI for Potriots PSI Halftime- ts PSI Haitime = 12.5146 to 12.845 to 11.443 2. Suppose we'd like to know if the mean PSI for the Colts' footballs changed significantly from pregame to halftime. The pregame PSI for all Colts footballs was 13 a. Perform a two sided, one sample test of hypothesis pair: Ho.lColts PSI Hatume = 13 HAi coits PS! Halftime # 13 To do this in JMP, start from the Analyze Distribution output you used to answer the questions in part 1, then click the red arrow by "PSI Halftime" and select "Test Means". See the end of class notes 11 for more details, Test statistic: 14 p-value b. what would the p-value for the previous test be if the alternative had been H·AColts PSI Halfbrme

Explanation / Answer

2 a)
Test Statistic, t: -14.4955

P-Value: 0.0000

b) P-Value: 0.0000

c) Numerator : (11.16-13) = -1.84
Denominator : 0.421/sqrt(11) = 0.1269
d) Correct Answer: (F)
