For this analysis, the “exercise” variable was divided into 4 approximately equally-sized groups: (1) low exercise, (2) below average exercise, (3) above average exercise, and (4) high exercise. Is there sufficient evidence to suggest that these 4 groups significantly differ in average BMI scores (using an alpha level of .05)?  Examine the results in the above tables and provide a brief write-up of your interpretation of these results

The BMLsax file includes a sample of 1000 adults measured on the following variables:
bmi – Body Mass Index
sex
calorie - Daily Caloric Intake
exercise – Number of minutes of Exercise per Week
income – Monthly Salary in Dollars
foed exR - Monthly Expenditure on Food in Dollars
education – Education Level in Years
density – Residential Density (High, Medium, and Low
-
For this analysis, the "exercise" variable was divided into 4 approximately equally-sized groups: (1) low exercise, (2) below average exercise, (3) above average exercise, and (4)
high exercise. Is there sufficient evidence to suggest that these 4 groups significantly differ in average BMI scores (using an alpha level of .05)? Examine the results in the above
tables and provide a brief write-up of your interpretation of these results in the space below. Once completed save this document and submit using the assignment function of the
course.
