Suppose that, in fact, the total cholesterol level of all men aged 20-34 follows the Normal distribution with mean u = 182 milligrams per deciliter (mg/dL) and standard deviation o = 37 mg/dL. Use Table A if necessary. Choose an SRS of 1000 men from this population. Now what is the probability that x falls within +2 mg/dL of u? Round your answer to four decimal places. 0.8790 probability: Incorrect

Question 6 of 11 > Stacked ロ□ O Attempt 1 Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). To estimate 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 for all 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. 0.3688 probability: Incorrect 0V1433
