1. Are the mean rates of return different at the α=0.05 level of significance? Use technology to find the F-test statistic for this data set. F0=______? (Round to two decimal places as needed.) 2. Determine the P-value and state the appropriate conclusion below. Since the P-value is _____? there is not enough evidence to reject the null hypothesis. Thus, we cannot conclude that the mean rates of return are different at the α=0.05 evel of significance. (Round to three decimal places as needed.)

A stock analyst wondered whether the mean rate of return of financial, energy, and utility stocks differed over the past 5 years. He obtained a simple random sample of eight companies from each of the three sectors and obtained the 5-year rates of return shown in the accompanying table (in percent).
