1.You are given the results of student scores for an SAT practice test. You are also given the mean and standard deviation. Can you find the percent of students who scored below a 500?
No. I don’t know if the data is normally distributed or not. 
No – I am far too busy to wonder how many students scored below a 500! 
Yeah – Lemme at ’em!
No. I need the variance. 
2.What does P(E|F) mean?
The probability of F following E.
The probability of E occurring, given that F occurs.
The probability of E divided by F
E|F times P
3.An expected value is a type of mean.
True
False
4.What is the Z score for the population mean?
z = -1
z = 0
z = 1.1
Z = -3

6.You are looking at data regarding the amount of hearing loss experienced by people who attended concerts of the 80’s hair metal band, “Hearing Impaired Cheetah.” The data is normally distributed and you have the mean and standard deviation. You would like to find the percentage of your data that falls within Z = -1.5 and Z = 1. How do you do this?
