Explain which of the following is a two-tailed test, a left-tailed test, or a right-tailed test.

a. H0: µ = 45, H1: µ > 45

b. H0: µ = 23, H1: µ ≠ 23

c. H0: µ > 75, H1: µ < 75

Show the rejection and non-rejection regions for each of these cases by drawing a sampling distribution curve for the sample mean, assuming that it is normally distributed.
