A test of =:H0μ55 versus ≠:H1μ55 is performed using a significance level of =α0.10 . The value of the test statistic is =z−1.72 . Part: 0 / 3 0 of 3 Parts Complete Part 1 of 3 Determine whether to reject H0 . Since the test statistic (Choose one) in the critical region, we (Choose one) H0 at the =α0.10 level.
