Textbook Question
Chapter 14.3, Problem 27E
The article “Human Lateralization from Head to Foot: Sex-Related Factors” (Science, 1978: 1291–1292) reports for both a sample of right-handed men and a sample of right-handed women the number of individuals whose feet were the same size, had a bigger left than right foot (a difference of half a shoe size or more), or had a bigger right than left foot.
| L > R | L = R | L < R | ||
| Men | 2 | 10 | 28 | 40 |
| Women | 55 | 18 | 14 | 87 |
Does the data indicate that gender has a strong effect on the development of foot asymmetry? State and test the appropriate hypotheses.

Your personal trainer suggests that you supplement with at least 10 grams of creatine, 39 grams of L-glutamine, and 90 grams of BCAAs each week. You are thinking of combining Xtend and Gainz to provide you with the required nutrients. How many servings of each should you combine to obtain a week's supply that meets your trainer's specifications at the least cost? (If an answer does not exist, enter DNE.)
