Question

The participants’ mean age was 63.2 years (SD = 7.6, range 36–76), and 54.9% of the sample was female. The average duration of known type 2 diabetes was 10.6 years (±6.6, 3–36). Based on the World Health Organization classification of obesity,32 the study sample included 32.9% overweight (BMI = 25–29.99), 33.7% obese grade I (BMI = 30–35), and 33.4% obese grade II (BMI . 35) subjects. Furthermore, 61.3% of the sample achieved the minimally recommended activity level of 1.000 kcal per week (32.7% did not achieve this level, and 6% did not answer all questions on the FFkA). To establish the level of 1.000 kcal, the author was guided by a review of Warburton et al33 on the health benefits of PA.

Question:

Based on the data in the Results section, how likely is it that a person would have been a diabetic for 45 years?

Very likely since this number is well within plus or minus 1 SD of the mean

Unlikely since this number is well within plus or minus 1 SD of the mean

Very likely since this number is well outside of plus or minus 3 SD of the mean

Unlikely since this number is well outside plus or minus 3 SD of the mean

Very likely since this number is well within plus or minus 1 SD of the mean

Unlikely since this number is well within plus or minus 1 SD of the mean

Very likely since this number is well outside of plus or minus 3 SD of the mean

Unlikely since this number is well outside plus or minus 3 SD of the mean

Explanation / Answer

Based on the data in the Results section, it is unlikely  that a person would have been a diabetic for 45 years since this number is well out side plus or minus 3 SD of the mean.

i.e., 45 >10.6 + (3*6.6) = 30.4

Hence the correct option is

Unlikely since this number is well outside plus or minus 3 SD of the mean
