Unformatted text preview: P(X>4.5), since the bar for 5 actually stretches from 4.5 to 5.5, and we need to include the entire bar of 5 and move right. If we wished to say P(r less than or equal to 5), this would correspond to P(X<5.5) , since again the bar ends at 5.5, and we need to include the whole bar for 5 and move left. Example : n = 25, p = .3, find P(r>11) . Use the normal approx to the binomial . Example : The probability is .65 that an animal survives migration to its winter location. For a random sample of 500 animals, use the normal approximation to the binomial to find the probability that between 310 and 340 animals (inclusive) survive migration. Example : The probability that a driver regularly wears a seatbelt is known to be . 75. Find the probability that in a random check of 100 cars, 70 or fewer drivers were wearing their seatbelts. Use the normal approximation....
