A research organization tested microwave ovens. At α = 0.10, is there a significant difference in the average prices of the three types of oven?

A computer printout for this exercise is shown. Use the P-value method and the information in this printout to test the claim.

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.
