In: Statistics and Probability
The National Turkey Association wants to experiment with the effects of three different feed mixtures on weight gain in poults. Because no experience exists regarding the three mixtures, no assumptions regarding the population distribution of weights exist. To study the effects of the three mixtures, five poults were given feed A, six were given feed B, and five were given feed C over a three-week time period. Test at the 0.1 level the hypothesis that there is no effect of feed mixture on weight. (Round your answers to 3 decimal places.)
Weight (in pounds) | ||
Feed Mixture A | Feed Mixture B | Feed Mixture C |
12.9 | 12.5 | 10.7 |
11.3 | 11.2 | 12.4 |
11.2 | 12.9 | 10.9 |

from above:
H0 :the distributions are the same
Ha: they are not the same
Reject H0 if H > 4.605
Computed H = 2.157
There is not sufficient evidence that the mean weights of the turkeys are not the same.
