Answer #1

ANSWER:

Given that,

Testing: H0:μ= 38.375 H1: μ> 38.375 Your sample consists of 40 subjects, with a mean of 39.9 and a sample standard deviation (s) of 4.65. Calculate the test statistic, rounded to 2 decimal places. t=?

Mean = = 39.9

Standard deviation = s = 4.65

Sample size = n = 40

Test statistic = t = (-μ) / (s/sqrt(n))

t = (39.9-38.375 ) / (4.65 /sqrt(40))

t = 1.525 / (4.65 /sqrt(40))

t = 2.07418

t = 2.07 (Rounded to two decimal places)
