The following is sample information. Test the hypothesis that the treatment means are equal. Use the 0.02 significance level.
|Treatment 1||Treatment 2||Treatment 3|
a. State the null hypothesis and the alternate hypothesis.
H0: (Click to select) The treatment means are not all the same. The treatment means are the same.
H1: (Click to select) The treatment means are the same. The treatment means are not all the same.
b. What is the decision rule? (Round the final answer to 2 decimal places.)
Reject H0 if the test statistic is greater than .
c. Compute SST, SSE, and SS total. (Round the final answers to 3 decimal places.)
SS total =
d. Complete the ANOVA table. (Round the SS, MS, and F values to 3 decimal places.)
e. State your decision regarding the null hypothesis.
(Click to select) Reject Do not reject H0.
Ho: The treatment means are the same.
Ha: The treatment means are not all the same.
|Applying one way ANOVA: (use excel: data: data analysis: one way ANOVA: select Array):|
Reject H0 if the test statistic is greater than 6.23
since test statistic <critical value
Do not reject H0.
