Question 991124: In the table below, percentages are probabilities of 15-year survival without coronary heart disease, stroke, or diabetes in men aged 50 years with selected combinations of risk factors. Here "BMI" stands for body mass index, an index of weight adjusted for height. The World Health Organization gives the following classifications: "normal" 18.5 to 24.9; "grade 1 overweight" 25.0 to 29.9; "grade 2 overweight" 30.0 to 39.9; "grade 3 overweight" 40.0 or higher http://www.webassign.net/craudql1/5-1-042.gif
A 50-year-old man who has never smoked, has normal weight, and is active has a much higher probability of being healthy than a man who smokes, is very overweight, and is inactive. Is the probability twice as high, less than twice as high, or more than twice as high?

Look at the number in the upper left corner of the table. Compare it to the number in the lower right corner of the table. Is it twice as high, less than twice as high, or more than twice as high?
