" . . CHAPTER 5 Answer the question. . .:. (1) Suppose that weight of adolescents is being studied by a health organization and that the accompanying tables describes the probability distribution for three randomly selected adolescents, where x is the number who are considered morbidly obese. Is it unusual to have no obese subjects among three randomly selected adolescents? x/ P(x) 0 0.111 1 0.215 2 0.450 3 0.224 A) No B) Yes Determine whether the given procedure results in a binomial distribution. If not, state the reason why . 12) Rolling a single "loaded" die 39 times, keeping track of the "fives" rolled. A) Not binomial: the trials are not independent B ) Not binomial: there are more than two outcomes for each trial . C) Not binomial: there are too many trials. . D) Procedure results in a binomial distribution. . . . Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial 13) n=12, x=5, p=0.25 Find the indicated probability. 14) An airline estimates that 90% of people booked on their flights actually show up. If the airline books 71. people on a flight for which the maximum number is 69, what is the probability that the number of people who show up will exceed the capacity of the plane? Find the standard deviation, a, for the binomial distribution which has the stated values of n and p. Round your answer to the nearest hundredth. 15 ) n = 721; p = 7
