A university administrator is interested in determining the mean salary for all 84 faculty members at the university. To calculate the mean, the administrator adds all of the salaries together and divides by the number of salaries (84) to arrive at the mean salary of $64,000.Is this mean salary of $64,000 considered to be a sample mean or population mean, and which symbol would be used to denote this mean?

Answer

From the statement, we know that the administrator computes the mean by adding all the salaries of the faculty members, i.e. he is computing the mean by using all the population.

We conclude that the mean computed by the administrator is the mean of all the population, which symbol is μ.

Step-by-step explanation

The mean salary considered is the population mean, which has the symbol μ.
