Answer:

$z_{stat} = -1.50$

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 108

Sample mean, $\bar{x}$ = 107

Sample size, n = 110

Alpha, α = 0.02

Population standard deviation, σ = 7

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{107 - 108}{\frac{7}{\sqrt{110}} } = -1.50$

The test statistic is -1.50
