If you can, find the mean and standard deviation. if you cannot, explain why A survey of adults found that 54% have used a multivitamin in the past 12 months. You randomly select 40 adults and ask them if they have used a multivitamin in the past 12 months Select the corredt answer below and,if necessany, il in the answer boxes within your choice O A. No, because nq

Explanation / Answer

p = 0.54

n = 40

np = 40 * 0.54 = 21.6

nq = 40 * ( 1 - 0.54) = 18.4

mean = n * p = 40 * 0.54 = 21.6

Standard deviation = sqrt(n * p * (1-p)) = sqrt(40 * 0.54 * 0.46) = 3.15

Option-C) yes, the mean is 21.6 and Standard deviation is 3.15
