This question concerns approximations to the Normal Distribution. (i) Explain in your own words how the Poisson Approximation to the Normal Distribution arises and why this is important. (ii) It is known that in the Australian Population, 15% of people are over 180cm tall. Showing your working, what is my chance of having at least 11 people of over 180cm tall with a sample size of 100. (iii). If I had a sample of at least 1000 people (from the Population in (ii)), would that be enough to be 99.9% sure of obtaining at least 100 people over 180cm tall? Please explain your reasoning.
