Given the following sample information, test the hypothesis that the treatment means are
equal at the .05 significance level.
Treatment 1 Treatment 2 Treatment 3
8 3 3
11 2 4
10 1 5
a. State the null hypothesis and the alternate hypothesis.
b. What is the decision rule?
c. Compute SST, SSE, and SS total.
d. Complete an ANOVA table.
e. State your decision regarding the null hypothesis.
f. If H0 is rejected, can we conclude
The solution gives the details of comparing three treatment means using one-way ANOVA. SSE,SST and SSTotal are given.
