Answer: Population Mean : \mu=23\text{ minutes}

Sample mean : \overline{x}=26\text{ minutes}

Step-by-step explanation:

The population mean the average of the population on a given characteristics.

We have already given population mean as \mu=23\text{ minutes}

Now, the sample of commute time  12 employees are

25,33,26,29,17,29,42,19,15,52,11,14

\text{Sample mean =}\dfrac{\text{Sum of observations}}{\text{Sample size}}\\\\=\dfrac{312}{12}=26\\\\\Rightarrow\overline{x}=26\text{ minutes}
