A binomial experiment is given. Decide whether you can use the normal distribution toapproximate the binomial distribution. If you can, find the mean and standard deviation. If youcannot, explain why.A survey found that 89% of parents of teenagers have taken their teenager's cell phone orInternet privileges away as a punishment. You randomly select 17 parents of teenagers andask them whether they have taken their teenager's cell phone or Internet privileges away as apunishment.Select the correct answer below and, if necessary, fill in the answer boxes to complete yourchoice.OA. Yes, the mean is and the standard deviation is(Round to two decimal places as needed.)OB. No, because nq < 5.OC. No, because np < 5.Mins

61% percent of adults in a certain country believe that life on other planets is plausible. You randomly select 5 adults and ask them whether they believe that life on other planets is plausible. The random variable represents the number of adults who believe that life on other planets is plausible. Find the mean, variance, and standard deviation of the binomial distribution for the random variable, then interpret the results. The mean= 3.85The variance= 0.89 The standard deviation= 0.94 On average, _________ out of every 5 adults in the country believe that life on other planets is plausible. In most samples of 5 adults, the number of adults who think life on other planets is plausible would differ from the mean by no more than _________.
