Nutrition education programs, which teach clients how to lose weight, reduce cholesterol intake, or reduce fat intake through better eating patterns, have been growing in popularity. The nurse in charge of one such program at a local hospital wanted to know whether the programs actually work to improve health measures. A random sample was drawn of 33 clients who attended a nutrition education program. The study recorded the following health measures: weight, cholesterol levels, total dietary fat intake per average day, total dietary cholesterol intake per average day, and percent of daily calories from fat. These data were gathered both before and 3 months after the program. The researcher also determined the clients' genders, ages, and heights. The data are stored in the following way:

Column A: Gender (1 = female; 2 = male)

Column B: Age

Column C: Height (in meters)

Columns D and E: Weight, before and after (in pounds)

Columns F and G: Cholesterol Level, before and after

Columns H and I: Total Dietary Fat Intake per average day, before and after (in grams)

Columns J and K: Dietary Cholesterol Intake per average day, before and after (in milligrams)

Columns L and M: Percent Daily Calories from fat, before and after

Each of you should have already received 2 assigned variables. For each of the variables you are assigned, answer the following research questions. Consider each variable individually. Don't try to incorporate both of your variables into one test for any of the research questions. Also, be aware that you may need to reorganize the data to run the tests and/or create new variables. Remember that required conditions are dependent on the test chosen, so you MUST decide the test for each question BEFORE you check required conditions.  You WILL have separate required conditions for each research question!

a) In terms of each of the health measures (weight, cholesterol level, fat intake, cholesterol intake, calories from fat), is the program a success?

b) Does age impact the amount of reduction in each measure (weight, cholesterol level, fat intake, cholesterol intake, calories from fat)?

c) Do males and females differ in the amount of reduction for each measure (weight, cholesterol level, fat intake, cholesterol intake, calories from fat)?

You answer should be written in narrative form with appropriate graphs and output included as needed and should be submitted in one Word document. You should use Excel for all your analysis and the p-value criteria to make your decisions. I do not need to see the seven-step hypothesis testing process, but be sure you include everything I specify below:
