solutions Of the items produced in a assembly line, 7% are underweight. A quality control engineer plans to sample 80 items. Find the a) probability that fewer than 6 of them will be underweight; b) standard deviation in the number of underweight items in samples of this size. An average of 24 cars per hour pull up at a drive up window. Find the: a) probability that at least 8 cars pull up in the next 25 minutes; b) the standard deviation in the number of cars that pull up in a 15 minute period.
