# Question: Consider the null hypothesis H0 5 A random

Consider the null hypothesis H0: µ = 5. A random sample of 140 observations is taken from a population with σ = 17. Using α = .05, show the rejection and non-rejection regions on the sampling distribution curve of the sample mean and find the critical value(s) of z for the following.

a. A right-tailed test

b. A left-tailed test

c. A two-tailed test

a. A right-tailed test

b. A left-tailed test

c. A two-tailed test

Explain how the tails of a test depend on the sign in the alternative hypothesis. Describe the signs in the null and alternative hypotheses for a two-tailed, a left-tailed, and a right-tailed test, respectively.
