Question

Pulse rates of women are normally distributed with a mean of 77.5 bpm and a standard deviation of 11.6 bpm what are the values of the mean and standard deviation have to converting all pulse races to women to the scores?

Answer 1

To convert pulse rates of women to z-scores, subtract the mean and divide by the standard deviation.

Step-by-step explanation:

To convert pulse rates of women to z-scores, we need to subtract the mean and divide by the standard deviation.

Z = (X - mean) / standard deviation

For example, if we want to convert a pulse rate of 85 bpm:

Z = (85 - 77.5) / 11.6 = 0.64

So the z-score for a pulse rate of 85 bpm is 0.64.
