Identifying Unusual Values with the Range Rule of Thumb. In Exercises 33–36, use the range rule of thumb to determine whether a value is unusual.
Pulse Rates of Females Based on Data Set 1 in Appendix B, females have pulse rates with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. Is it unusual for a female to have a pulse rate of 99 beats per minute? (All of these pulse rates are measured at rest.) Explain.

Identifying Unusual Values with the Range Rule of Thumb. In Exercises 33–36, use the range rule of thumb to determine whether a value is unusual.
Pulse Rates of Females Based on Data Set 1 in Appendix B, females have pulse rates with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. Is it unusual for a female to have a pulse rate of 99 beats per minute? (All of these pulse rates are measured at rest.) Explain.
ANSWER:Answer :
Step 1 of 1 :
Given Pulse Rates of Females Based on Data Set 1 in Appendix B, females have pulse rates with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute.
We know that mean μ = 77.5 and standard deviation σ = 11.6
According to the range rule of thumb, most values should lie within 2 standard deviations of the mean.
We can therefore ide
