Answer 1

Answer:

26

Step-by-step explanation:

Mean (Average) 26

Median 25.5

Range 41

Mode 29, appeared 2 times

Geometric Mean 23.569888915944

Largest 52

Smallest 11

Sum 312

Count 12

Answer 2

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

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