Unformatted text preview: of an 80% chance that an admitted student will attend Harvard, what is the probability that Harvard will not have enough dormitory room spots for the freshman students? Solution: We will use normal approximation to solve this question. First lets verify the conditions: np = 1640 > 10 and n (1p ) = 2050(0 . 2) = 410 > 10 So X is approximately N ( X , X ) = N (1640 , 18 . 11). P ( X > 1655) = P ( Z > 16551640 18 . 11 ) = P ( Z > . 828) = 0 . 204 . Page 1 of 1...
