Assume the resting heart rates for a sample of individuals are normally distributed with a mean of 85 and a standard deviation of 5. Use the 68-95-99.7 rule to find the following quantities:

The relative frequency of rates less than 95 using the68-95-99.7 rule is

(Round to three decimal places asneeded.)

b. The relative frequency of rates greater than 90 using the68-95-99.7 rule

(Round to three decimal places asneeded.)

c. The relative frequency of rates between 75 and 85 using the68-95-99.7 rule is

(Round to three decimal places asneeded.)
