Question 9 0/1 pt 9 10 99 @ Details Scores for a common standardized college aptitude test are normally distributed with a mean of 518 and a standard deviation of 102. Randomly selected men are given a Test Prepartion Course before taking this test. Assume, for sake of argument, that the test has no effect. If 1 of the men is randomly selected, find the probability that his score is at least 585.7. P( x > 585.7) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. If 10 of the men are randomly selected, find the probability that their mean score is at least 585.7. P( X > 585.7) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. If the random sample of 10 men does result in a mean score of 585.7, is there strong evidence to support the claim that the course is actually effective? Yes. The probability indicates that it is unlikely that by chance, a randomly selected group of students would get a mean as high as 585.7. O No. The probability indicates that it is possible by chance alone to randomly select a group of students with a mean as high as 585.7. Submit Question Question 10 C0/1 pt O 10 7 99 @ Details The town of KnowWearSpatial, U.S.A. operates a rubbish waste disposal facility that is overloaded if its 5054 households discard waste with weights having a mean that exceeds 27.36 lb/wk. For many different weeks, it is found that the samples of 5054 households have weights that are normally distributed with a mean of 27.01 lb and a standard deviation of 12.56 lb. What is the probability that the disposal facility is overloaded in a randomly selected week? P( 3 > 27.36) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. Is this an acceptable level, or should action be taken to correct a problem of an overloaded system? No, this is not an acceptable level because it is not unusual for the system to be overloaded. Yes, this is an acceptable level because it is unusual for the system to be overloaded. Submit
