In a completely randomized experimental design, 6 experimental units were used for each of the 4 levels of the factor (i.e., 4 treatments):

Source of Variation

Sum of Squares

Degrees of Freedom

Mean Square

Between Treatments

2434220

3

811406.7

Error (Within Treatments)

3883910

20

194195.5

Total

6318130

23

1.    What is the null and alternative hypothesis for this ANOVA test?

2.   Calculate the F test statistic.

3.   What is the rejection rule for the F test at the 0.05 level of significance?

4.   What is the conclusion of the F test? Please give reason.
