Expert Solution

Step 1

Given Information :

A random sample of 10 employees of a company was selected to estimate the mean one way commute time for all employees at the company. The mean and standard deviation of the sample mean were 38 minutes and 6 minutes, respectively.

Here ,

Sample size : n = 10

Sample mean : $\bar{x}$ = 38 minutes

Sample standard deviation : s = 6 minutes

The margin of Error: The margin of error can be calculated by depending on whether you have parameters from a population or statistics from a sample:

The margin of error = Critical value x Standard deviation for the population.
