Question

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. answer the following questions.
what are the values of the mean and standard deviation after converting all pulse rates of women to z scores using
z = \frac{(x - \mu)}{\sigma}?
\mu = \square
\sigma = \square

Explanation:

Step1: Recall the formula for z - score

The formula for the z - score is \(z=\frac{x - \mu}{\sigma}\), where \(\mu\) is the mean and \(\sigma\) is the standard deviation.

Step2: Identify the values from the problem

We are given that the mean \(\mu = 77.5\) (beats per minute) and the standard deviation \(\sigma=11.6\) (beats per minute).

Answer:

\(\mu = 77.5\), \(\sigma = 11.6\)
