A new sales training program has been instituted at a rent-to-own company. Prior to the training, 10 employees were tested on their knowledge of products offered by the company. Once the training was completed, the employees were tested again in an effort to determine whether the training program was effective. Scores are known to be normally distributed. The sample scores on the tests are listed next. Use pretest score as µ₁ for population 1 and post-test score as µ₂ for population 2, or µ_D as the mean of the difference calculated as pre-test score minus post-test score. Which of the following are the appropriate hypotheses to determine if the training increases scores? A) H₀: µ₁ - µ₂ ≥ 0, H_A: µ₁ - µ₂ 0 C) H₀: µ_D ≥ 0, H_A: µ_D0
