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=?​

Answer 1

Explanation:

To convert all pulse rates of women to z-scores, we use the formula:

z = (x - μ) / σ

where x is the pulse rate, μ is the mean, and σ is the standard deviation.

Substituting the given values, we get:

z = (x - 77.5) / 11.6

Therefore, after converting all pulse rates of women to z-scores, the mean will be 0 and the standard deviation will be 1.
