scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. certificates are given to students whose scores are in the top 2% of those who took the test. this means that they scored better than 98% of the other test takers. marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. show all work to determine whether marcus’ score was high enough to earn a certificate. write a letter to marcus explaining whether or not he will be receiving a certificate. include a brief summary of your statistical analysis in your letter.
