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
We have such equation
6x+3=4x+9 /-4x subtract 4x both sides
6x-4x+3=4x-4x+9
2x+3=9 /-3 subtract 3 both sides
2x=6 /:2 divide both sides by 2
x=3 - its result
