Consider the following hypothesis test. Ho : M1 - /2 = 0 Ha : /1 - 12 # 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 71 = 35 n2 = 40 D1 = 13.6 T2 = 10.1 $1 - 5.2 82 = 8.5 a. What is the value of the test statistic (to 2 decimals)? b. What is the degrees of freedom for the t distribution (round the answer to the previous whole number)? c. What is the p-value? Use Table 2 from Appendix B. The area in the upper tail is - Select your answer - ; two-tailed p-value is - Select your answer - d. At a = 0.05, what is your conclusion? p-value is - Select your answer - Ho
