Test the claim that µi is different than 42. A random sample of size 18 yields ¤1 = 15.05 and s = 1.5, while a random sample of size 18 yields 2 = 15.8 and s = 1.1. Use a = 0.05. 1. The population distribution requirement for this test is: O Need a normally distributed population sinceni and n2 < 30 O None since this is a Z-test O Need a normally distributed population since this is a T-test O None since n, and n2 > 30 The hypotheses are: O Ho:p < p2; Ha:p1 > p2 O Ho: p 1 = µ2; Ha: µ1 # µ2 O Ho: µ1 > µ2; Ha: µ1 < µ2 O Ho:p1 p2; Ha:pi # p2 O Ho: µi < µ2; Ha: µ1 > µ2 O Ho:p1 2 p2; Ha: p1 < p2 2. This is a O twoO rightOleft tailed test and the distribution used is OT since both o values are not known OZ since both o values are known OZ since testing two proportions The Degrees of Freedom (use the simple estimate discussed in the notes, not the messy formula) are O 17 ON/A; this is a Z-test
