. Question 5 v A random sample of 40 exam scores yields :3 : 70.7 and .5 : 7.1. At 0: : 0.10, test the claim that the standard deviation of test scores exceeds 6.3' 1. The alternate hypothesis is Ha: 'I'I'Ii' cr > 5.3 'I'I'Ii' cr > 7.1 -":::- 02 :> 7.1 -':::- 02 :> 6.3 2' This is a "3:.3' right"3.:.3' left? two tailed test with d.f. = 3a. The 5T5 [to 2 decimals] is x2 : 3b' The P-value [to 3 decimals) is: 4a. At or = 0.10, the decision is: '13 Reject Ho '3' Accept Ho '3' Do not reject Ho '3' Accept Ha 4b. The conclusion is: '3' There is sufficient evidence to support the claim that the standard deviation of test scores exceeds 6.3 '3' There is insufficient evidence to reject the claim that the standard deviation of test scores exceeds 6.3 '33:? There is insufficient evidence to support the claim that the standard deviation of test scores exceeds 6.3 '33:? There is sufficient evidence to reject the claim that the standard deviation of test scores exceeds 6.3
