Nutrition education programs, which teach their clients how to lose weight or reduce cholesterol levels 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. A random sample of 33 clients who attended and nutrition education program for those with elevated cholesterol levels was wrong. Study recorded the weight, cholesterol levels, total dietary fat intake per average day, total dietary cholesterol intake per average day, and percent of diet calories from fat. These data were gathered both before and three months after the program. The researchers also determined the gender, age, and height of the clients. The data are stored in the following way: column 1: gender (number one equal female; number two equal male) column 2: age column 3: height (in meters) column 4 & 5: weight, before and after (in kilograms) column 6 & 7: cholesterol level, before and after column 8 & 9: total dietary fat intake per average day, before and after (in grams) column 10 & 11: dietary cholesterol intake per average day, before and after (in milligrams) column 12 & 13: percent daily calories from fat, before and after the nurse would like the following information: 1. in terms of each of weight, cholesterol level, fat intake, cholesterol intake, and calories from fat, is the program a success? 2. Does gender affect the amount of reduction in each of weight, cholesterol level, fat intake, cholesterol intake, and calories from fat? 3.
