Question 5 of 14 Ho : u = 15 kg Hi: p > 15kg Level of significance: o = 0.025 Sample size: n = 36 Test statistic: t = 2.089 Unknown population standard deviation T-Distribution Table a. Determine the critical value(s) for the proposed hypothesis test. Round to three decimal places if necessary b. Conclude whether to reject the null hypothesis or not based on the test statistic. O Reject O Fail to Reject c. State the decision error type that is possible. O Type I Error O Type II ErrorQuestion 6 of 14 A random sample of m = 21 securities in Economy A produced mean returns of *1 = 5.8% with s, = 2.1% while another random sample of no = 16 securities in Economy B produced mean returns of X 2 = 4.9% with $2 = 2.2%. At a = 0.02, can we infer that the returns differ significantly between the two economies? Assume that the samples are independent and randomly selected from normal populations with equal population variances ( 0 12 = 02?). T-Distribution Table a. Calculate the test statistic. 1 = 0.000 Round to three decimal places if necessary b. Determine the critical value(s) for the hypothesis test. Round to three decimal places if necessary c. Conclude whether to reject the null hypothesis or not based on the test statistic. O Reject O Fail to Reject
