We would subtact 3 from both sides allowing the equation to simplify to -8c=32
We would then divide both sides by -8 to equal -4
The final answer C=-4
Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 108
Sample mean,
= 107
Sample size, n = 110
Alpha, α = 0.02
Population standard deviation, σ = 7
Formula:
Putting all the values, we have

The test statistic is -1.50
3 is the answer! Have a nice day!
