Question 1161336: If 80% of job applicants are
able to pass a computer literacy test, find the mean,
variance, and standard deviation of the number of
people who pass the examination in a sample of
150 applicants. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! mean is np=150*0.8=120 applicants
variance is np(1-p)=120*0.2=24 applicants^2
sd is sqrt (V)=4.90 applicants
