Assume the distribution of the resting pulse rates for a sample of individuals are bell- curved with a mean of 75 and a standard deviation of 14. Use the 68-95-99.7 rule to find the following quantities. Show a well labelled bell-curve to verify your answers.

a. Percentage of pulse rates less than 75.

b. Percentage of pulse rates greater than 61.

c. Percentage of pulse rates between 33 and 117.

d. Percentage of pulse rates between 33 and 103.

e. Percentage of pulse rates between 47 and 89.
