Consider the following hypothesis test. Ho : / - 12 = 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 721 = 35 12 = 40 I1 = 13.6 T2 = 10.1 81 = 5.3 82 = 8.7 a. What is the value of the test statistic (to 2 decimals)? 2.14 X b. What is the degrees of freedom for the t distribution (round the answer to the previous whole number)? 75 c. What is the p-value? Use Table 2 from Appendix B. The area in the upper tail is between 0.01 and 0.025 ; two-tailed p-value is between 0.02 and 0.05 v d. At a = 0.05, what is your conclusion? p-value is | less than or equal to 0.05, reject Ho
