# Question

Refer to Exercise 19.17. Use the Tukey-Kramer W to determine which pairs of diets have significantly different mean weight gains.

In Exercise 19.17

A study of the difference in the effects of six newly created diets on the weight gain of young rabbits is proposed. Because weight varies considerably amongst young rabbits, it is proposed to block the experiment based on litters. There are 10 litters of rabbits available for the study, but they are of varying sizes. The minimum litter size is three. Therefore, only three of the six diets can be observed in any particular litter. A balanced incomplete block design was proposed for this situation. The researcher conducted the study and obtained the following weight gains.

Do the data provide significant evidence of a difference in mean weight gains amongst the six diets? Use the formulas given in this Section 19.4 to obtain your answers.
