Subjects in a study by Dabonneville et al. included a sample of 40 men who claimed to engage in a variety of sports activities (multisport). The mean Body Mass Index (BMI) for these men was 22.41 with a standard deviation of 1.27. A sample of 24 male rugby players has a mean BMI of 27.75 with a standard deviation of 2.64. Is there sufficient evidence for one to claim that in general, rugby players have a higher BMI than the multisport men? Perform the test at the 0.01 level of significance.
