Show complete solution. Consider the following null and alternative hypothesis. Ho:μ = 120 versus Ha: μ > 120 A random sample of 81 observations taken from this population produced a sample mean of 123.5 and a sample standard deviation of 15. If this test is made at 2.5% significance level, would you reject the null hypothesis?
