Answer:

The value of test statistic is -2.

Step-by-step explanation:

The following information is missing in the question.

The population mean is 12 minutes.

We are given the following in the question:

Population mean, μ = 12 minutes

Sample mean, \bar{x} = 8 minutes

Sample size, n = 36

Population standard deviation, σ = 12 minutes

Formula:

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

Putting all the values, we have

z_{stat} = \displaystyle\frac{8 - 12}{\frac{12}{\sqrt{36}} } = -2

The value of test statistic is -2.
