A company institutes an exercise break for its workers to see if this will improve job satisfaction, as measured by a questionnaire.  Scores for 10 randomly selected workers before and after the implementation of the exercise program are shown. Higher scores indicate improved job satisfaction. Worker # 1 2 3 4 5 6 7 8 9 10 Before 34 28 29 45 26 27 24 15 15 27 After 33 36 50 41 37 41 39 21 20 37 If a hypothesis test were to be conducted to test for a significant change in mean difference between satisfaction scores before and after (before – after) the exercise program for each worker, what would be the correct null and alternative hypotheses?
