One-sided test Suppose you carry out a significance test of H0 :m = 5 versus Ha :m < 5
Chapter 9, Problem 71(choose chapter or problem)
One-sided test Suppose you carry out a significance test of \(H_0: \ \mu=5\) versus \(H_a: \ \mu<5\) based on a sample of size \(n=20\) and obtain \(t=-1.81\).
(a) Find the P-value for this test using Table B or technology. What conclusion would you draw at the 5% significance level? At the 1% significance level?
(b) Redo part (a) using an alternative hypothesis of \(H_a: \ \mu \ne 5\).
