Homework Help: statistics

Posted by Darcy on Monday, September 12, 2011 at 8:23pm.

It appears to people who are mildly obese are less active than leaner people. One study looked at the average number of minutes per day that people spend standing or walking. Among mildly obese people, minutes of activity varied according to the N(373,67) distribution. Minutes of activity for lean people had the N(526,107) distribution. Within what limits do the active minutes for 95% of the people in each group fall? Use the 68-95-99.7 rule.

I have no idea where to even begin to try and answer this. I am so lost. Please help!! Thanks!
