> Women’s pulse rates are normally distributed with a mean of 68.5 beats per minute and a standard deviation of 10.9 beats per minute. What is the z-score for a woman having a pulse rate of 65 beats per minute?
Homework Answers
Solution :
Given that,
mean = 
= 68.5
standard deviation = 
= 10.9
x = 65
Using z-score formula,
z = x -
/
= (65 - 68.5 ) / 10.9
= -3.5 / 10.9
= -0.32
The z-score = - 0.32
