Question: A random sample of 20 observations produced a sample mean of 9.5. Find the critical and observed z-values for each of the following and test each hypothesis at α = 0.05. Write a separate conclusion for each hypothesis. The underlying population standard deviation is known to be 3.5 and the population distribution is normal:
a. H0: μ = 8.75; H1: μ ≠ 8.75
b. H0: μ = 8.75; H1: μ > 8.75
