Step-by-step explanation:

Given that the number of vacation days taken by the employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days.

Since it is mentioned in general he employees of a company this is population std deviation. If sample normally for a sample size of ... this is std deviation would be given.

Sample std deviation is the square root of variance of all the items from the sample mean. Thus this is purely arrived from the sample observations taken.

Whereas population std deviation is square root of variance for all the entries in the population.
