Claim: the mean pulse rate (in beats per minute) of adult males is equal to 69 bpm. for a random sample of 170 adult males, the mean pulse rate is 70.1 bpm and the standard deviation is 10.5 bpm. find the value of the test statistic. the value of the test statistic is nothing.

1.3659

Step-by-step explanation:

Given: The mean pulse rate (in beats per minute) of adult males is equal to 69 bpm.

For a random sample of 170 adult males, the mean pulse rate is 70.1 bpm and the standard deviation is 10.5 bpm.

To Find: Find the value of the test statistic.

Solution:

n =170

Since sample size is greater than 30

So, we will use z test

The mean pulse rate = x= 70.1 bpm

Standard deviation=

n = 170

Formula :

Substitute the values

Hence  the value of the test statistic is 1.3659
