A manager of restaurant knows that 30% of his customers are professional truckers. The manager surveys the next 12 customers who come into the restaurant to determine if they are professional truck drivers or not.Does this situation meet the binomial requirements? Why or why not?Address the five conditions of a binomial distribution in the textbook.What is the random variable in this problem? (i.e., what does X represent and what values can it have?)What is the probability that exactly 4 are truck drivers?What is the probability that 5 or fewer are truck drivers?What is the probability that at least 4 are truck drivers?What is the probability that at most 4 are truck drivers?What is the mean number of customers out of a sample of 12 that you would expect to be truck drivers? What is the standard deviation of the distribution?
