# Question: Pulse rates of women are normally distributed with a mean

Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute (based on Data Set 1 in Appendix B).

a. What are the values of the mean and standard deviation after converting all pulse rates of women to z scores using z = (x - µ) > σ?

b. The original pulse rates are measured with units of “beats per minute.” What are the units of the corresponding z scores?
