Question
The Center for Disease Control and Prevention (CDC) states that adults should engage in at least 75 min of vigorous-intensity aerobic activity or 150 min of moderate-intensity aerobic activity weekly. Researchers gathered data from a random sample of adults who participated in the 2011-2012 National Health and Nutrition Examination Survey (NHANES). The NHANES data are shown in the relative frequency table and are available to download in a variety of formats. Crunchlt! CSV Excel JMP Mac Text Minitab PC Text R SPSS TI Calc What is the relative frequency of adults who are engaging in less than the minimum amount of recommended moderate-intensity physical activity weekly (less than 150 min)? Give your answer to two decimal places. relative frequency =Explanation / Answer
From the relative frequwncy table we can see that:
Relative frequency of adults engaging in 0-49 min of moderate intensity aerobic activity is 47.54%
Relative frequency of adults engaging in 50-99 min of moderate intensity aerobic activity is 32.77%
Relative frequency of adults engaging in 100-149 min of moderate intensity aerobic activity is 11.85%
So Relative frequency of adults engaging in less than the minimum amount of recommended moderate intensity physical activity weekly is:
47.54 + 32.77 + 11.85
= 92.16%
