f we assume the random noise in the simulation is uniform, we can say that if we repeat this simulation over and over again, 95% of the time the value we get will be within 2 standard deviations either way of the average. In other words, there’s about 1 chance in 40 that you will get a value lower than average -2 and 1 chance in 40 that you’ll get a value higher than average + 2 . What range will 95% of your numbers land in

33% of college students say they use credit cards because of the rewards program. you randomly select 10 college students and ask each to name the reason he or she uses credit cards. find the probability that the number of college students who say they use credit cards because of the rewards program is (a) exactly two, (b) more than two, and (c) between two and five inclusive. if convenient, use technology to find the probabilities.
