Consider the following hypothesis test. Ho : /1 - 1 = 0 Ha : /1 - /2 # 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 71 = 35 12 = 40 $1 = 13.6 $2 = 10.1 $1 = 5.4 52 = 8.6 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 = v; two-tailed p-value is |- Select your answer - d. At a = 0.05, what is your conclusion? p-value is - Select your answer - Ho
