The average annual salary for federal government is $41,979. Use this figure as the population mean and assume the population standard deviation = $5,000
Suppose that a random sample of fifty federal employees will be selected froths population .
What is the value of the standard error of the mean?
What is the probability that the sample mean will be within $ 1,0000.00 of the population mean?
How would the probability change if the sample size were to increased to 100
What is the probability that the sample mean will be more than $41,979.00?
