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.
