how do you know the score of 137.22 is -1.25?? where did you find that

[@SonOfAbba]

Remember the Z score formula he mentioned which is Z = (x - xbar) /S. Xbar is the mean of 100 and S is the standard deviation of 16.
Z = (80 - 100) / 16 ...... which equals -1.25

How do i change my calculator so that prompts me to put in the values in he correct order, instead having to remember them like on the ti83

[@NUKINATOR44]

what is infinity on the TI 82 plus?

[@kent633]

Julian Mireles you can use 1 x 10^99 there isn't an infinity button on the calculator.

The NormCDF of professors not being able to effectively teach????? Kent is not in that area/percent. Thank you sir.

[@PinoyAznLee]

How did he get z= -1.25

[@kent633]

PinoyAznLee if you take the number and subtract the mean then divide by the standard deviation (the z-score formula) you get (80-100)/16 =-1.25
