A) 2.78
B) 2.87
C) 3.01
D) 3.10
F Statistic
A statistical measure that determines the ratio of variance between groups to variance within groups in the context of ANOVA tests.
Significance Level
The threshold below which a p-value is considered statistically significant, often set at 0.05 or 5%.

Final Answer :
D
Explanation :
The critical value for F statistic with 3 degrees of freedom in numerator and 20 degrees of freedom in denominator at 5% level of significance is 3.10. Therefore, if the calculated F statistic is greater than 3.10, we reject the null hypothesis.
