Below are randomly selected scores for winning college basketball teams in each of three regions for a particular weekend. At the 0.10 level of significance is there sufficient evidence that there is a difference in mean scores by region?

Assume that all variables are normally distributed, that the samples are independent, and that the population variances are equal. Also, for each exercise, perform the following steps.
a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.
e. Summarize the results, and explain where the differences in the means are.
Use the traditional method of hypothesis testing unless otherwise specified.
