> 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?
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

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.5 bpm. For a random sample of 162 adult males, the mean pulse rate is 69.9 bpm and the standard deviation is 11.3 bpm. Complete parts (a) and (b) below.
Assume that an adult female is randomly selected. Suppose females have pulse rates that are normally distributed with a mean of 79.0 beats per minute and a standard deviation of 12.5 beats per minute. Find the probability of a pulse rate between 62 beats per minute and 73 beats per minute. (Hint: Draw a graph.) The probability is _______ .
