We are conducting an experiment to see if the amount of cooking oil we use makes a difference in the mean number of kernels popped when popping popcorn.  We have randomly assigned 36 bags of popcorn to be popped with no oil, 36 to be popped with 1/2 teaspoon of oil, and 36 bags to be popped with 1 teaspoon of oil. Each bag contains the same number of unpopped kernels of corn to start equally. (50 kernels each, but you don’t need to use that number) Complete the ANOVA table to report the F-Test Statistic.

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 test statistic?
