Assume that females have pulse rates that are normally distributed with a mean of

mu equals 76.0μ=76.0

beats per minute and a standard deviation of

sigma equals 12.5σ=12.5

beats per minute. Complete parts​ (a) through​ (c) below.

a. If 1 adult female is randomly​ selected, find the probability that her pulse rate is between

7272

beats per minute and

8080

beats per minute.The probability is

nothing.

​(Round to four decimal places as​ needed.)

b. If

2525

adult females are randomly​ selected, find the probability that they have pulse rates with a mean between

7272

beats per minute and

8080

beats per minute.The probability is

nothing.

​(Round to four decimal places as​ needed.)
