Answer:

The value of the test statistic is -0.979

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 11.1 hours

Sample mean, $\bar{x}$ = 10.7 hours

Sample size, n = 24

Alpha, α = 0.05

Sample standard deviation, s = 2.0 hours

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 11.1\text{ hours}\\H_A: \mu \neq 11.1\text{ hours}$

We use two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{10.7 - 11.1}{\frac{2}{\sqrt{24}} } = -0.979$

Thus, the value of the test statistic is -0.979
