Question 18 Test the claim that /1 is less than /2. A random sample of size 20 yields x1 = 17.12 and s = 1.1, while a random sample of size 19 yields x2 = 17.5 and s = 1.5. Use a = 0.10. 1. The population distribution requirement for this test is: Need a normally distributed population since this is a T-test O None since n1 and n2 2 30 O Need a normally distributed population since n1 and n2 M2 O Ho: M1 2 12; Ha: /1 P2 O Ho:p1 2 p2; Ha: p1 a: '33:? Reject Ho since P 23 a '33:? Reject Ho since P E a The conclusion is: Q There is sufficient evidence to conclude that #1 is not less than #2 {333' There is insufficient evidence to conclude that #1 is Less than g '33:} There is sufficient evidence to conclude that p51 is less than #2 '33:? There is insufficient evidence to conclude that #1 is not Less than #2
