Suppose that a scholarship qualifying exam is given to a large number of students every year. Over the last 5 years, the exam results are normally distributed with a mean of 35 and a standard deviation of 7. Suppose over that period of time 10000 students took the testMake use of the empirical rule to answer these questions. Do not do any computations with Stat Crunch or the Tables to answer this question. If you use anything other than the Empirical Rule to answer this qustion, your answer will not be considered substantive. If you had received a 56, how many students (approximately) did better than you? What does that say about your score? What if your friend received a 28? How many students (approximately) had a lower score than youir friend? If the scholarship is awarded to 2.5% of the students who take the exam, aproximatly what would be the minimum score that would be needed to qualify?
