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

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. ​ ​

A) µ₁ is significantly different from µ₃ and there are no other significant differences.
B) µ₄ is significantly different from both µ₁ and µ₃, and there are no other significant differences.
C) µ₂ and µ₄ are significantly different from µ₁ and µ₃. There are no other significant differences.
D) µ₁ is significantly different from µ₄ and there are no other significant differences.
E) µ₂ is significantly different from both µ₁ and µ₃, and there are no other significant differences.
