A new cinema is under construction and the total number of the seats is to be determined.Assume that in this area, 1600 people will go to cinema everyday and for the probability for each person to choose this cinema is 3/4. The Following are the requirements for determining the seat quantity q:1) q is as large as possible2) The probability of "there are over 200 empty seats in one day" is no more than 0.1Hint: Central Limit Theorem

Answer:a) 1359 seatsStep-by-step explanation:We have a population of 1600 people. There is a probability p=0.75 of choosing this cinema for every individual.We could treat this problem as a binomial distribution problem, but because of n=1600 being bigger enough, we can treat this a normal distribution.The mean of this distribution can be estimated as:[tex]\mu=n*p=1600*0.75=1200[/tex]and its standard deviation as[tex]\sigma=\sqrt{n*p*(1-p)}=\sqrt{1600*0.75*0.25}=17.32[/tex]In the standard normal distribution (mean=0 and sd=1), the value z in which the probability P(x<z)=0.1 is z=-2.362.This z-value (z=-2.362) is equivalent to X=1159 in our distribution X=N(1200;17.32).[tex]X=\mu-z*\sigma=1200+2.362*17.32=1159[/tex]Then, can be said that there is a probability P=0.1 of having less than 1159 people in the cinema.If this probability correspond to a situation with 200 empty seats, the minimum amount of seats needed is 1159+200=1359 seats.
