Consider the following hypothesis test. Ho : /1 - M2 = 0 Ha : /1 - 12 + 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 n1 = 35 n2 = 40 1 = 13.6 X2 = 10.1 $1 = 5.8 $2 = 8.7 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. S The area in the upper tail is between 0.01 and 0.025 v ; 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 V Ho
