Test Ho : mu = 44 against H1 : mu < 44 given that the population variance is 1.5, alpha is .05, n = 100 and the sample mean is 43. Use alpha = .05. How much would the sample mean need to change in order for the test to turn out differently. Find beta under the assumption that the population mean is really 42.5.. Find the p-value
