Question 1059212
A random sample of 100items is selected from a population of size 350. 
What is the probability that the sample mean will exceed 199
if the population mean is 195and the population standard deviation equals  25? 
Hint: Use the finite population correction factor since the sample size is more than; 5% of the population size.)
---
fpc = sqrt[(N-n)/(N-1)]
---------------------
z(199) = (199-195)/fpc = [4/sqrt(25)][sqrt[(350-100)/(350-1)] = 0.9452
P(x-bar > 199) = P(z > 0.9452) = normalcdf(0.9452,100) = 0.1723
