Ive read through a small portion of the book right now and the owner of the book before me left some of the sample problems the teacher gave them without answers or how to solve them I understand some of it but I was hoping I could get specific information on how to do it here.

here is the sample problem

in 1992 the journal of the American Medical Association reported that the average body temperature is 98.2 with a SD of .7

What percent of people have a body temperature between 97.3 and 98.6

**o**now I know that roughly 68% are within a +-1 SD range and 95% are within +-2 SDs roughly.

(average was 98.2) so the smallest within 1sd is 97.5 the largest within 1 SD is 98.9

I could do the same within 2SD's as well

How would I figure out how to get the percent of people that have a body temperature between 97.3 and 98.6?

The previous owner of this sample question said their answer was 61.5% but did not show any work nor do I know if this is correct.

Thank you for your help
