Nutritionists Study the Impact of Four Different Diets on Women's

Question 35

Multiple Choice

Nutritionists study the impact of four different diets on women's vulnerability to vitamin B6 deficiency. The researchers randomly assigned adult women to one of four groups. Each group followed a specific diet. Let µ1, µ2, µ3, and µ4 represent the mean daily intake of vitamin B6 (in mg) for diets 1, 2, 3, and 4, respectively. The sample data are given in the table below. Use the 95% Tukey-Kramer procedure to identify the correct statement describing the differences among the diets. ​ Nutritionists study the impact of four different diets on women's vulnerability to vitamin B<sub>6</sub> deficiency.
