K Assume the resting heart rates for a sample of individuals are normally distributed with a mean of 85 and a standard deviation of 20. Use the 68-95-99.7 rule to find the following quantities. a. The relative frequency of rates less than 125 using the 68-95-99.7 rule is 0.975. (Round to three decimal places as needed.) b. The relative frequency of rates greater than 105 using the 68-95-99.7 rule is 0.160 (Round to three decimal places as needed.) c. The relative frequency of rates between 45 and 85 using the 68-95-99.7 rule is (Round to three decimal places as needed.)

Assume the resting heart rates for a sample of individuals are normally distributed with a mean of 85 and a standard deviation of 20. Use the 68-95-99.7 rule to find the following quantities. a. The relative frequency of rates less than 125 using the 68-95-99.7 rule is **0.975**. (Round to three decimal places as needed.) b. The relative frequency of rates greater than 105 using the 68-95-99.7 rule is **0.160**. (Round to three decimal places as needed.) c. The relative frequency of rates between 45 and 85 using the 68-95-99.7 rule is [missing value]. (Round to three decimal places as needed.)
