b. Determine the alternative hypothesis.

c. Classify the hypothesis test as two tailed, left tailed, or right tailed.

Right-tailed test: a. z = 1.24 b. z = −0.69 We have given the value obtained for the test statistic, z, in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine ...Each part of this exercise provides a scenario for a hypothesis test for a population mean. Decide whether the z-test is an appropriate method for conducting the hypothesis test. Assume that the population standard deviation ...x-bar = 23, n = 24, σ = 4, H0: μ = 22, Ha: μ ≠ 22 We have provided a sample mean, sample size, and population standard deviation.
