Is your breathing rate normal? Actually, there is no standard breathing rate for humans. It can vary from as low as 4 breaths per minute to as high as 70 or 75 for a person engaged in strenuous exercise. Suppose that the resting breathing rates for college-age students have a relative frequency distribution that is mound-shaped, with a mean equal to 12 and a standard deviation of 2.3 breaths per minute.
What fraction of all students would have breathing rates in the following intervals?
a. 9.7 to 14.3 breaths per minute
b. 7.4 to 16.6 breaths per minute
c. More than 18.9 or less than 5.1 breaths per minute
