In a certain population, 20% of the people have minor eye defect. A sample of 100 people is selected at random from this population. a. The mean number of people with minor eye defect in the sample is The standard deviation of the number of people with minor eye defect in the sample is If you use normal approximation to binomial and take continuity correction factor into account, then probability that 22 or less people (at most 22 people) in the sample have minor eye defect is Assume that number of the people having minor eye defect in the sample is binomial random variable denoted by Y, which is approximated with normal random variable X. Show some work to answer question b.
