Approximating Binomial Probabilities In Exercises 2328, determine whether you can use a 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 a binomial distribution to find the indicated probabilities Medicare A survey of U.S. adults found that 67% oppose raising theMedicare eligibility age from 65 to 67. You randomly select 80 U.S. adultsand ask them how they feel about raising the Medicare eligibility age from65 to 67.
