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. is this a case of sample standard deviation or population standard deviation? what are some differences between sample standard deviation and population standard deviation?

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.

step-by-step explanation: examine the two-step equation.

which property of operations allows you to add the same constant term to both sides?

multiplication property of equality

division property of equality

addition property of equality

subtraction property of equality
