Attached are two subject problems for review and completion. Please use MS EXCEL application to make the computations.

treatment 1 // treatment 2 // treatment 3
8 3 3
6 2 4
10 4 5
9 3 4

Test the hypothesis that the treatment means are equal. Use the .05 significance level.
1 state the null and the alternate hypothesis
2 what is the decision rule?
3 compute the components of variance (SST -treatment, SSE-error, and SS total)
4 complete an ANOVA table
5 state your decision regarding the null hypothesis

ANOVA
Test the hypothesis that the treatment means are equal. Use the .05 significance level.
1 state the null and the alternate hypothesis
2 what is the decision rule?
3 compute the components of variance (SST -treatment, SSE-error, and SS total)
4 complete an ANOVA table
5 state your decision regarding the null hypothesis

The null hypothesis tested is
H0: There is no significant difference in the mean of three treatments
H1: There is significant difference in the mean of three treatments.

Test Statistic used is ANOVA (F ...
