Consider the hypothesis test Ho : of = of against Mi: of * of. Suppose the sample sizes are n = 16 and n, = 21 and the sample standard deviations are s, = 1.8 and s, = 1.5. Usea = 0.05. a) Test the hypothesis. Find the P.value. Round your answer to three decimal places (e.g. 9.876). p = value= b) Construct a 95% two-sided confidence interval of a relations. Round your answers to two decimal places (e.g. 9.87)
