# ANOVA and Chi square analysis

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 ...
