The distribution of SAT scores is roughly normal. The mean on the SAT is a 1060 with a standard deviation of 195. Use the Z-table to answer the following questions. a) What is the probability of a randomly chosen student scoring below a 1200 on the SAT? b) What is the probability of a randomly chosen student scoring above a 1000 on the SAT? c) What is the probability that a randomly chosen student will score below 800 OR above 1200?

and1200?
e) Misty scored a 950 on the SAT. What percentile is she in?
