Question

1. The test statistic of z = -1.94 is obtained when testing the claim that p ? 5/8. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of ? = 0.05, should we reject H0 or fail to reject H0? d. Find the critical value(s).
