Question

The mean pulse rate​ (in beats per​ minute) of adult males is equal to 69 bpm. For a random sample of 162 adult​ males, the mean pulse rate is 69.6 bpm and the standard deviation is 11.3 bpm. Find the value of the test statistic.

Answer 1

0.6758

Explanation:

Given That:

Population Mean pulse rate (μ) = 69

Sample size (n) = 162

Sample mean (m) = 69.6

standard deviation (σ) = 11.3

Value of test statistic :

(m - μ) / (σ/√n)

(69.6 - 69) / (11.3 / √162)

0.6 / 0.8878118

= 0.6758
