Question Help Claim: The mean pulse rate (in beats per minute) of adult males is equal to 69 bpm. For a random sample of 152 adult males, the mean pulse rate is 70.4 bpm and the standard deviation is 11.2 bpm. Find the value of the test statistic The value of the test statistic is - (Round to two decimal places as needed.) DC emplate Discus.. Enter your answer in the answer box ?

Answer 1

The test statistic here is,

$t = \frac{\bar{X}-\mu}{s/\sqrt{n}}$

t Test for Hypothesis of the Mean
Data
Null Hypothesis                m=	69
Level of Significance	0.05
Sample Size	152
Sample Mean	70.4
Sample Standard Deviation	11.2
Standard Error of the Mean	0.9084
Degrees of Freedom	151
t Test Statistic	1.5411

Hence the value of test statistic is 1.54
