Problem #2 According to a recent study, 11% of all Americans eat fast food 4-6 times per week. You ask 500 people "Do you eat fast food 4-6 times per week?". The number of times that a subject replied "yes" is observed. a ) Explain why the number of people who respond "yes" follows a binomial distribution. b) Calculate the mean and standard deviation of the distribution. Round to the nearest hundredth if necessary. C) Recall that a value is unusual if it does not fall within 2 standard deviations of the mean. If you surveyed 500 people and 100 of them responded "yes", would this be considered unusual? Show support for your answer. Problem #2
