Transcribed Image Text:Determine whether you can use a normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate th
indicated probabilities and sketch their graphs. If you cannot, explain why and use a binomial distribution to find the indicated probabilities. Identify any
unusual events. Explain.
In a survey of U.S. adults, 19% said that they have participated in a clinical trial. You randomly select 210 U.S. adults. Find the probability that the
number who have participated in a clinical trial is (a) no fewer than 34, (b) more than 42, and (c) between 37 and 47 inclusive.
Determine whether a normal distribution can be used to approximate the binomial distribution. Choose the correct answer below.
OA. No, because nq < 5.
OB. No, because np < 5.
OC. Yes, because both np ≥ 5 and nq ≥ 5.
(a) Find the probability that the number who have participated in a clinical trial is no fewer than 34.
(Round to four decimal places as needed.)
