###### Aplitude test are normally distributed with mean of 500 and standard Scores for & common standardized college Randomly selected men are given Test Preparation Course before taking this test Assume , for sake deviation of 98. of argument that the preparation course has no effect randomly sclected, find the probability that his score at Icast 560.7. If ! of the men P(X > 560.7) = Enter your answer a5 number accurate t0 decimal places. If 15 of the men Jre randomly selected, find the probabi

aplitude test are normally distributed with mean of 500 and standard Scores for & common standardized college Randomly selected men are given Test Preparation Course before taking this test Assume , for sake deviation of 98. of argument that the preparation course has no effect randomly sclected, find the probability that his score at Icast 560.7. If ! of the men P(X > 560.7) = Enter your answer a5 number accurate t0 decimal places. If 15 of the men Jre randomly selected, find the probability that their mean score at least 560.7. P(M > 560.7) Enter your answer as number accurate t0 decimal places; Assume that any probability less than 5%/ sufficient cvidence conclude that the preparation course docs help men do better If the random sample of 15 men docs result in mean score of 560.7,is there strong evidence to support the claim that the course actually eflective? The probability indicates that it IS too possible by chance alone randomly select = group of students with [cam high as 560.7. Yes: The probability indicates that it Is (highly unlikely that by chance, randomly sclected group of students would get & mean as high as 560.7_
