For this exercise, we will be analyzing information on nutrition from the Rosner (2021 ) textbook at the end of Chapter 5 (page 142 ). For each of these problems, we will be using the information posted with the problems in the book and the information you gained from the chapter to respond to each item. HINT: You may wish to hand - calculate these problems using Table 3, The Normal Distribution in the Appendix (page 874 ), though you may find it simpler to use Excel and the NORMDIST function to solve each problem . An example of this is provided in Example 5.17 (page 125) of the textbook . For additional support , see the NORMDIST Tutorial from Microsoft here : NORMDIST Function Assignment Provide a response to each of the problems listed in the textbook for the Nutrition case (problems 5.6-5.9)

Nutrition Suppose that total carbohydrate intake in 12- to 14-year- old boys is normally distributed, with mean = 124 g/1000 cal and standard deviation = 20 g/1000 cal. 5.6 What percentage of boys in this age range have carbo- hydrate intake above 140 g/1000 cal? 5.7 What percentage of boys in this age range have carbo- hydrate intake below 90 g/1000 cal? Suppose boys in this age range who live below the poverty level have a mean carbohydrate intake of 121 g/1000 cal with a standard deviation of 19 g/1000 cal. 5.8 Answer Problem 5.6 for boys in this age range and economic environment. 5.9 Answer Problem 5.7 for boys in this age range and economic environment
