You can put this solution on YOUR website! A psychologist studied self esteem scores and found the sample data set to be normally distributed with a mean of 50 and a standard deviation of 5.
What is the z-score that cuts off the bottom 10.03% of this distribution?
Using a TI-84 calculator get invNorm(0.1003 = -1.2798
-------------------------------------------------------------
What is the raw score that cuts off the bottom 10.03% of this distribution?
Use the form x = z*s + u to find the raw score
x = -1.2798*5 + 50 = 43.6
