Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults found that 8% say their favorite sport is auto racing. You randomly select 400 adults and ask them to name their favorite sport. Complete parts (a) through (d). .... . Determine whether a normal distribution can be used to approximate the binomial distribution. Choose the correct answer below. A. No, because np < 5. B. No, because nq < 5. C. Yes, because both np 25 and nq 2 5. (a) Find the probability that the number of people who say auto racing is their favorite sport is at most 39. (Round to four decimal places as needed.)
In a recent survey, approximately 90% of U.S. adults own a cell phone. Let's assume this can be modeled as a binomial distribution. In a group of 20 randomly selected adults, what is the standard deviation of the number of adults you would expect to own a cell phone?
