The table shows results for the Body Mass Index (BMI) of random samples of men and women. The BMI is the weight (kg) divided by the square of the height (m).
|
Male BMI |
Female BMI |
|
n = 40 _ s = 7.39 |
n = 40 _ s = 5.34 |
At the 5% LOS, do the data suggest the men have greater variability in BMI compared to women?

Visual Basic: The federal government developed the body mass index (BMI) to determine ideal weights. Body mass index is calculated as 703 times the weight in pounds, divided by the square of the height in inches, and then round to the nearest whole number. Define a function that accepts a person’s weight and height as inputs and returns the person’s health status (A BMI of 19 to 25 corresponds to a healthy status).

9) The body mass index (BMI) of an individual is a measure used
to judge whether an individual is overweight or not. A BMI between
20 and 25 indicates a normal weight. In a survey of 750 men and 750
women, the Gallup organization found that 203 men and 270 women
were normal weight. Construct a 90% confidence interval to gauge
whether there is a difference in the proportion of men and women
who are normal weight.
