?1 = 5	?2 = 4	?3 = 5
̅̅̅ ?1 = 5	̅̅̅ ?2 = 5.25	̅̅̅ ?3 = 4.6
?2 = 2.12 1	?2 = 2.22 2	?2 = 2.07 3

Expert Solution

Answer:

To test, H0:Means are equal

H1:At least one inequality exist.

Group 1,Group 2,Group 3 means Diet 1,Diet 2 and Diet 3

Reject H0 iff p value is less than =0.05

p value=0.899> 0.05

Hence we fail to reject the null hypothesis and conclude that the means are not different
