Question
Consider the following hypothesis test. H₁ H₁-H₂ = 0 H₂ : ₁ - 20 The following results are from independent samples taken from two populations. Sample 1 721 = 35 113.6 = 5.4 $1 a. What is the value of the test statistic (to 2 decimals)? 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 ✓ d. At a = 0.05, what is your conclusion? p-value is less than or equal to 0.05, reject Sample 2 n₂ = 40 b. What is the degrees of freedom for the distribution (round the answer to the previous whole number)? Ho 2 = 10.1 82 = 8.1 ; two-tailed p-value is between 0.02 and 0.05
