Ho : M1 - 12 = 0 Ha : (1 - 12 # 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 n1 = 35 722 = 40 I1 = 13.6 I2 = 10.1 $1 = 5.2 $2 = 8.5 a. What is the value of the test statistic (to 2 decimals)? 2.11 b. What is the degrees of freedom for the t distribution (round the answer to the previous whole number)? 73 c. What is the p-value? Use Table 2 from Appendix B. The area in the upper tail is greater than 0.20 ; two-tailed p-value is greater than 0.40 d. At a = 0.05, what is your conclusion? p-value is less than 0.05, do not reject Ho
