Test H 0 : μ 1 = μ 2 vs H a : μ 1 > μ

Question:

Test H0: μ1= μ2vs Ha: μ1> μ2using the paired data in the following table:

Situation 1 125 156 132 175 153 148 180 135 168 157 Situation 2 120 145 142 150 160 148 160 142 162 150


Use a t-distribution and the given matched pair sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distribution of the differences is relatively normal. Assume that differences are computed using d = x1 ˆ’ x2.
