list K Assume that you have a sample of n, =9, with the sample mean X, = 46, and a sample standard deviation of S, = 5, and you have an independent sample of n, = 13 from another population with a sample mean of X2 = 37 and the sample standard deviation S2 = 8. Complete parts (a) through (d) below. on 4 a. What is the value of the pooled-variance tSTAT test statistic for testing Ho H1 = H2? ion 5 STAT = (Round to two decimal places as needed. ) tion 6 b. In finding the critical value, how many degrees of freedom are there? degrees of freedom (Simplify your answer ) stion 7 c. Using a significance level of a = 0.01, what is the critical value for a one-tail test of the hypothesis Ho , S H2 against the alternative H, : My > #2? The critical value is estion 8 (Round to two decimal places as needed.) d. What is your statistical decision? uestion 9 O A. Do not reject Ho because the computed tSTAT test statistic is less than the upper-tail critical value. O B. Reject Ho because the computed STAT test statistic is greater than the upper-tail critical value. Question 10 O C. Do not reject Ho because the computed tSTAT test statistic is greater than the upper-tail critical value. O D. Reject Ho because the computed tSTAT test statistic is less than the upper-tail critical value. Question 11 Time Remaining: 01:08:40 Next
