Chapter 12, Problem 2P

Nutrition

Researchers compared protein intake among three groups of postmenopausal women: (1) women eating a standard American diet (STD), (2) women eating a lacto-ovo-vegetarian diet (LAC), and (3) women eating a strict vegetarian diet (VEG). The mean ± 1 sd for protein intake (mg) is presented in Table 12.29.

What is the p-value from the test performed in Problem 12.1?

Perform a statistical procedure to compare the means of the three groups using the critical-value method.
