Based on Data Set 1 "Body Data" in Appendix B, males have pulse rates with a mean of 69.6 beats per minute and a standard deviation of 11.3 beats per minute. Is a pulse rate of 50 beats per minute significantly low or significantly high? (All of these pulse rates are measured at rest.) Explain.
Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high.
