Use ONLY the Standard Normal Tables (Link: https://drive.google.com/file/d/0B5fn2hlYT0lAUlQ5a05aSUV6eTg/view) to answer the following...
A set of exam scores is normally distributed and has a mean of 60 and a standard deviation of 9. What is the probability that a randomly selected score will be greater than 77.1?
Answer =(round to four decimal places)
Note: Be careful...only use theZ Table (link: https://drive.google.com/file/d/0B5fn2hlYT0lAUlQ5a05aSUV6eTg/view) here and round z scores to two places since that's what the table uses...do not use technology or the 68-95-99.7 Rule.
