A random sample of 26 standard metropolitan statistical areas (SMSAs) was selected and ratio (per 1000) of registered voters to the total number of persons 18 years and over was recorded in each area. The data is given below. At 0.05 significance level, test the research hypothesis that μ, the average ratio, is greater than 675. Test the hypothesis using two approaches: the rejection region approach, and the p-value approach.
