Consider the hypothesis test Ho: o? = o; against H : o # %. Suppose the sample sizes are n, = 16 and n2 = 21 and the sample standard deviations are s, = 1.8 and $2 = 1.5. Use a = 0.05. a) Test the hypothesis. Find the P-value. Round your answer to three decimal places (e.g. 9.876). p - value = i v Ho. b) Construct a 95% two-sided confidence interval of ofrelations. Round your answers to two decimal places (e.g. 9.87). S
