Testing:

H0:μ=15.08H0:μ=15.08

H1:μ>15.08H1:μ>15.08

Your sample consists of 25 subjects, with a mean of 15.2 and
standard deviation of 2.24.

Calculate the test statistic, rounded to 2 decimal places.

t=

Answer #1

We are given a sample of 25 subjects, thus:

Sample size, n = 25

The sample has a mean of 15.2, thus:

Sample mean, = 15.2

Moreover, the sample has a standard deviation of 2.24,
thus:

Sample standard deviation, s = 2.24

Moreover, under the null hypothesis the value of the population mean μ is 15.08, thus:

Value of the population mean μ under H_{0},
= 15.08

Now, the value of the test statistic is given by:
