Nutrition education programs, which teach their clients how to lose

     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.      Does age affect the amount   of reduction in weight, cholesterol level, fat intake, cholesterol intake,   and calories from fat cholesterol?
