# Question

A right-tailed test with α = 0.01.

Determine the critical value(s) for a one-mean z-test. For each exercise, draw a graph that illustrates your answer.

Determine the critical value(s) for a one-mean z-test. For each exercise, draw a graph that illustrates your answer.

## Answer to relevant Questions

A two-tailed test with α = 0.05. Determine the critical value(s) for a one-mean z-test. For each exercise, draw a graph that illustrates your answer. The P-value for a hypothesis test is 0.083. For each of the following significance levels, decide whether the null hypothesis should be rejected. a. α = 0.05 b. α = 0.10 c. α = 0.06 Left-tailed test: a. z = −0.74 b. z = 1.16 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 ...Explain why considering outliers is important when you are conducting a one-mean z-test. x-bar = 20, n = 24, σ = 4, H0: μ = 22, Ha: μ ≠ 22 We have provided a sample mean, sample size, and population standard deviation. In each case, use the one-mean z-test to perform the required hypothesis test at the 5% ...Post your question
