Answer: The value of test statistic is 2.442.

Step-by-step explanation:

Since we have given that

n = 238

Sample mean = 23.2 minutes

Standard deviation = 20.26 minutes

Hypothesis :

$H_0:\mu=20\\H_a:\mu\neq 20$

So, the test statistic value would be

$z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{23.2-20}{\dfrac{20.26}{\sqrt{236}}}\\\\z=2.442$

Hence, the value of test statistic is 2.442.
