Suppose that the variable under consideration is normally distributed in each of two populations and that the population standard deviations are equal. Further, suppose that you want to perform a hypothesis test to decide whether the populations have different means, that is, whether . If independent simple random samples are used, identify two hypothesis-testing procedures that you can use to carry out the hypothesis test.
13.20 Figure shows side-by-side boxplots of independent samples from three normally distributed populations having equal standard deviations. Based on these boxplots, would you be inclined to reject the null hypothesis of equal population means? Why?
Fill in the missing entries in the partially completed one-way ANOVA tables.

We have provided data from independent simple random samples from several populations. In each case, determine the following items.
a. SSTR
b. MSTR
c. SSE
d. MSE
e. F

In this problem, consider an F-curve with .
Identify the degrees of freedom for the numerator.
