A researcher wishes to test the effects of excerise on the ability to complete a basic skills test. He designs a pre-test and post-test to give to each participant. You believe that there was a decrease in the scores. You believe the population of the differences is normally distributed, but you do not know the standard deviation. When calculating difference use Post-test minus Pre-test. pre-test post-test 41 45 71 100 87 61 53 71 74 76 Ο Ho: la < 0 HA: Md Which of the following are the correct hypotheses?
