2. What proportion of the population has resting heart rates below 74 bpm? Below 64 bpm?
3. What proportion of the population has resting heart rates between 62 and 76 bpm?
4. An aerobics instructor thinks that his class has an unusually low resting heart rate. His class of 16 students has a Meal), heart rate (X) of 68 limn. What is the z score for the class mean?
