# Question: Explain which of the following is a two tailed test a

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

a. H0: µ = 12, H1: µ < 12

b. H0: µ < 85, H1: µ > 85

c. H0: µ = 33, H1: µ ≠ 33

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.
