1. Suppose the scores for high school seniors on the verbal portion of the SAT test have a population mean of 509 and a population standard deviation of 112. a. List the population and the variable. b. What do you know about the population distribution of SAT scores for high school seniors? (i.e. shape, center, spread) c. Suppose we randomly select 56 high school seniors from this population. What would you expect the shape, mean and standard deviation of the...
SAT Verbal scores denoted by the random variable X are known to be normally distributed with mean of 500 and standard deviation of 100 based on data obtained from the college board system. a) Find the probability that a randomly selected score is less than 600? b)Find the probability that a randomly SAT score is between 350 and 700? c) Find the probability that a randomly selected SAT score is greater than 550? d) What should be the minimum SAT...
(1 point) Scores for men on the verbal portion of the SAT-I test are normally distributed with a mean of 509 and a standard deviation of 112. (a) If 1 man is randomly selected, find the probability that his score is at least 582.5. (b) If 12 men are randomly selected, find the probability that their mean score is at least 582.5. 12 randomly selected men were given a review course before taking the SAT test. If their mean score...

Scores for the verbal portion of the SAT-I test are normally distributed with a mean of 509 and a standard deviation of 112. Randomly selected men are given the Columbia Review Course before taking the SAT test. Assume that the course has no effect. a) If 16 students are randomly selected, find the sample mean and the sample standard deviation.
