Question 3. Suppose that the breathing rates for college-age students have a mound-shaped distribution, with a mean equal to 16 and standard deviation of 1.5 breaths per minute.
A. What is the proportion of all students that have breathing rates between 145 and
17.5 breaths per minute?
B. What is the proportion of all students that have breathing rates between 13 and
17.5 breaths per minute?
C. What is the proportion of all students that have breathing rates higher than 17.5
breaths per minute?
D. If a college-age student is chosen at random, what is the probability that the
student has breathing rate higher than 19 breaths per minute?
