This question has to do with z-scores...
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.

ahhhh.... standard deviations eh.... where my ti-83 at?
well 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
95% falls at the 2 line; and that result is .4772; or 47.72% at most
2000*.4772 = answer maybe? ....954.4 that dint work
is a calculator for it i think
.02275 is what that gives me
what to do with it I aint got a clue lol
hmm it won't let me put the 0.5 anywhere though just keeps saying 0.0000
lol me either.
i put in the mean 2000
the sd 400
and choose below 1200 for the 5%
i got a 1342 on the bottom part of it lol
yea i got that too but i dont really know what it means lol
i think it means pick c :)
lol okay. wth! its only one question haha thank you sooooo much for your help!!
