Set of null and alternative hypothesis

Question

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

Source of Variation	Sum of Squares
Between Treatments	14302
Error (Within Treatments)
Total	42321

1. What could be a set of null and alternative hypothesis for this experiment?
2. Find MSTR and MSE.
3. Find the test statistic and critical value of the F test at the 0.05 level of significance.
4. What conclusion can you draw on the hypotheses? Please give reason.
