A random sample of 100 observations from a population with standard deviation 60 yielded a sample mean of 110.
a.Test the null hypothesis that μ = 100 against the alternative hypothesis that μ > 100, using α = .05 Interpret the results of the test.
b.Test the null hypothesis that μ = 100 against the alternative hypothesis that μ ≠ 100, using α = .05. Interpret the results of the test.
c.Compare the results of the two tests you conducted. Explain why the results differ.
