(1) Summarize the data by whether children participated in the meal preparation or not.Use an appropriately labelled table to show the results.Also include a graphical presentation that shows the distribution of calories for participants vs. non-participants.Describe the shape of each distribution and comment on the similarity (or lack thereof) between the distributions in each population.

(2) Does the mean calorie consumption for those who participated in the meal preparation differ from 425?Formally test at the 0.05 level using the 5 steps outlined in the module.

(3) Calculate a 90% confidence interval for the mean calorie intake for participants in the meal preparation.Interpret the confidence interval.

(4) Formally test whether or not participants consumed more calories than non-participants at the 0.05 level using the 5 steps outlined in the module.

(5) Are the assumptions of the test used in (4) met?How do you know?
