Question

?Claim: The mean pulse rate? (in beats per? minute) of adult males is equal to 69 bpm. For a random sample of 151 adult? males, the mean pulse rate is 70.3 bpm and the standard deviation is 10.7 bpm. Find the value of the test statistic.

The value of the test statistic is __________

Answer 1

Solution:

Given that,

= 69

= 70.3

s = 10.7

n = 151

The test statisc t is,

t = ( -  ) /  (s /n)

t =( 70.3 - 69) / (10.7 / 151 )

t = (1.3 *  151 /10.7 )

t = 1.3*151 /10.7

t = 1.49

Test staistic = 1.49
