Suppose the alternative hypothesis in a hypothesis test is: "the population mean is less than 60". If the sample size is 50 and alpha = .05, the critical value of z is __. 2.05 1.645 -1.645 -1.96 1.96

Consider the following hypothesis test H0: p ≤ 66% ; H1 : p > 66%. The significance level used for this test on the proportion of the population is: α= 5%. A simple random sample of size n =500 from this population gives a proportion equal to 70%. Calculate the statistical value of the variable Z test (z-score) for rejecting or not H0 0.97 1.645 -1.888 1.95 1.888 1.94 -1.94

In a hypothesis test with hypotheses H0: p <= 0.58 and H1: p > 0.58, a random sample of size 900 produced a sample proportion of 0.60. The test is to be made at the 2.5% significance level. What is the critical value of z?
