Step 1 :We are given a binomial experiment where n=60 (the number of adults selected) and p=0.59 (the probability that an adult has used a multivitamin in the past 12 months).
Step 2 :We need to check if the binomial distribution can be approximated by a normal distribution. This is possible if both np and nq are greater than 5, where q is the probability of failure and is equal to 1-p.
Step 3 :First, calculate q as 1-p, which gives q = 1 - 0.59 = 0.41.
Step 4 :Next, calculate np and nq. np = 60 * 0.59 = 35.4 and nq = 60 * 0.41 = 24.6.
Step 5 :Since both np and nq are greater than 5, we can use the normal distribution to approximate the binomial distribution.
Step 6 :The mean of a binomial distribution is np, so the mean is 35.4.
Step 7 :The standard deviation of a binomial distribution is \(\sqrt{npq}\). Calculate the standard deviation as \(\sqrt{60 * 0.59 * 0.41} \approx 3.81\) (rounded to two decimal places).
Step 8 :Final Answer: Yes, the mean is \(\boxed{35.4}\) and the standard deviation is \(\boxed{3.81}\) (Round to two decimal places as needed).
