1) In ANOVA, what is the quantity that measuresthe variability between the groups of interest?

2) To determine whether the test statistic (F*) of ANOVA is statistically significant, F* can be compared to a critical value (Fcritical). What two pieces of information are needed to determine the critical value (Fcritical)?

3) Suppose the critical region for a certain test of the null hypothesis is of the form F > 9.48773 and the computed value of F* from the data is 1.86. Then:

a) The hypothesis test is two-tailed.

b) The significance level is given by the area to the right of 9.48773 under the appropriate F distribution.

c) None of the options.

d) H0 should be rejected.

e) The result is statistically significant
