A recent random sample of 458 Americans showed that 197 exercised for 30 minutes or more on 2 or fewer days per week, 121 exercised for 30 minutes or more on 3 or 4 days per week, and 140 exercised for 30 minutes or more on 5 or more days per week. At the 0.01 significance level, test the claim that the survey results follow the same distribution as in the report.
