According to a study, the probability that a randomly selected teenager shopped at a mall at least once during a week was 0.67. let x be the number of students in a randomly selected group of 50 that will shop at a mall during the next week. (a) compute the expected value and standard deviation of x. (round your answer to two decimal places.) hint [see example 5.] expected value standard deviation (b) fill in the missing quantity. (round your answer to the nearest whole number.) there is an approximately 2.5% chance that or more teenagers in the group will shop at the mall during the next week.
