The College Board reported the following mean scores for the three parts of the SAT (The WorldAlmanac, 2009):Critical reading502Mathematics515Writing494Assume that the population standard deviation on each part of the test is 100.a) What is the probability that a random sample of 90 test takers will provide a sample meantest score within 10 points of the population mean of 502 on the Critical reading part of thetest?b) What is the probability that a random sample of 90 test takers will provide a sample meantest score within 10 points of the population mean of 515 on the Mathematics part of thetest? Compare this probability to the value computed in part (a).Submission Directions:The assignment has to be submitted via Blackboard. Each student will be permitted onesubmission to Blackboard only. Each student needs to ensure that the document submittedis the correct one.
