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, = 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
We use two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Thus, the value of the test statistic is -0.979
