This question has to do with zscores...
A dean must distribute salary raises to her faculty for next year. She has decided that the mean raise is to be $2000, the standard deviation of raises is to be $400, and the distribution is to be normal. She will attempt to distribute these raises on the basis of merit, meaning that people whose performance is better get better raises. The 5% of the faculty who have done nothing useful in years will receive no more than $ _________ each.

Best ResponseYou've already chosen the best response.0z = xmu/omega omega = sqrt(n.p.q) right? and mu=n.p

Best ResponseYou've already chosen the best response.0lol...ok; then mu = 2000 and omega then is 400 right?

Best ResponseYou've already chosen the best response.0and the 5% is the smaller portion of the distribution. but I don't know how to if its the z score that gives you the 0.05 or if its something else

Best ResponseYou've already chosen the best response.02000 + 400 is one deviation 2000 + 800 is 2 deviations 2000 + 1200 is 3 deviations right?

Best ResponseYou've already chosen the best response.0those in the out liers are more than 2 standards so they get a raise of 2000  1200 = 800 right?

Best ResponseYou've already chosen the best response.02000  2(400) = 1200; but thats just an educated guess...

Best ResponseYou've already chosen the best response.0well to my understanding, if the 5% is in the smaller portion of the distribution, then you look up0.05 there and get the z score. then just stick that value int he equation and solve for x but its not working

Best ResponseYou've already chosen the best response.095% falls at the 2 line; and that result is .4772; or 47.72% at most 2000*.4772 = answer maybe? ....954.4 that dint work
