We know that the mean weight of men is greater than the mean weight of women, and the mean height of men is greater than the mean height of women. A person's body mass index (BMI) is computed by dividing weight (kg) by the square of height (m).
A random sample of 70 females has a mean BMI of 29.10 with standard deviation 7.39, while a random sample of 80 males has a mean BMI of 28.38 with standard deviation 5.37.
Use a significance level of 0.3 to test the claim that females appear to have a greater mean BMI than males.
