Hi all,

I have an assignment to do with a database of 380 observations (numbers going from 30000 to 80000).

Q.1 I need to calculate at first the population mean proportion for 50,000or less.

Q.2 Then I need to compare the mean proportion of 65,000 or more with the one in Q1.


Somebody can explain me what's the difference between the population mean and the population mean proportion ?

Thanks in advance for your answer
