... Let μ1 = the true mean number of defects produced by machine A. Let μ2 = the true mean number of defects produced by machine B. H0: μ1 – μ2 = 0 and Ha: μ1 – μ2 ≠ 0 We use a two-sample t test for the difference between means. The conditions for this procedure are given in the problem: both samples ar ...

... Statement of problem: The problem statement is either “Test at the 5% significance level to see if the mean income is at least 20000,” or “Test at the 5% significance level to see if the mean income is less than 20000.” These statements are opposites. Since the first statement contains an implicit e ...
