QUESTION:
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 Males Based on Data Set 1 in Appendix B, males have pulse rates with a mean of 67.3 beats per minute and a standard deviation of 10.3 beats per minute. Is it unusual for a male to have a pulse rate of 45 beats per minute? (All of these pulse rates are measured at rest.) Explain.
ANSWER:Answer :
Step 1 of 1 :
Given Pulse Rates of Males Based on Data Set 1 in Appendix B, males have pulse rates with a mean of 67.3 beats per minute and a standard deviation of 10.3 beats per minute.
We know that mean μ = 67.3 and standard deviation σ = 10.3
According to the range rule of thumb, most values should lie within 2 standard deviations of the mean.
We can
