Answer: 8 minutes to 28 minutes

Step-by-step explanation:

To include 95% of all employees, it will be 2 standard deviations from the mean. Two above and two below. Each is 5 min. So add 10 and subtract 10 from 18.

On the Gaussian Curve, about 68.3% are included within the first standard deviation above and below the mean. Then about 27.2% are added in the second standard deviation.
