Toestimate the mean score u of those who took the MCAT on your campus, you will obtain the scores of an SRS of students.The scores follow a Normal distribution, and from published information, you know that the standard deviation of scores forall MCAT takers is 10.8. Suppose that (unknown to you) the mean score of those taking the MCAT on your campus is 510.If you choose one student at random, what is the probability that the student's score is between 505 and 515?Use Table A or software to calculate your answer. Give your answer to four decimal places.0.3688probability:Incorrect0V1433
