You gave little context, so here is a few solutions.
POSSIBLE #1:
assuming s is a variable
---> Simplify ×
to
---> Collect like terms.
---> Simplify.
POSSIBLE #2: (assuming s is not relevant)
Simplifying
4x + -12 = 16 + 8x
Reorder the terms:
-12 + 4x = 16 + 8x
Solving
-12 + 4x = 16 + 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
-12 + 4x + -8x = 16 + 8x + -8x
Combine like terms: 4x + -8x = -4x
-12 + -4x = 16 + 8x + -8x
Combine like terms: 8x + -8x = 0
-12 + -4x = 16 + 0
-12 + -4x = 16
Add '12' to each side of the equation.
-12 + 12 + -4x = 16 + 12
Combine like terms: -12 + 12 = 0
0 + -4x = 16 + 12
-4x = 16 + 12
Combine like terms: 16 + 12 = 28
-4x = 28
Divide each side by '-4'.
x = -7
Simplifying
x = -7

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
