Answer:
Population mean= mu = μ= $102,342
Step-by-step explanation:
Here
Sample size= n= 15
Population mean= mu = μ= $102,342
Population standard deviation = sigma = σ =$21,756
The population mean is given by mu = μ
Both the means , the sample mean and the population mean give the same measure but there is difference in their calculations and usage.
The population mean mu is calculated by using the population size N but the sample mean x bar is calculated using sample size.
In the given question the sample size is given of the students whereas the mean salaries for attorneys in New York City gives the population mean because the attorneys in New York City contains all the attorneys given in the city. It is not a sample.
The population gives all the members of the group. So here none is missing.
