Suppose W, X, and Y follow binomial distributions with the number of trials and probability of success as indicated below. W follows a binomial distribution with w =10 trials and probability of success Pw = 0.1 X follows a binomial distribution with ny =4 trials and probability of success py = 0.25 Y follows a binomial distribution with ny =4 trials and probability of success py = 0.1 (a) Find Uw, My, and My, the respective means of W, X, and Y. X ? HW = 0 Hx = 1 My = 0 (b) The histograms of three binomial distributions are shown below. Match each of W, X, and Y with the histogram of its distribution.

What is the probability that the experiment results in exactly 4 successes? Do not round your intermediate computations, and round your answer to three decimal places. (If necessary, consult a list of formulas.) X 5 ? Suppose that the New England Colonials baseball team is equally likely to win a game as not to win it. If 5 Colonials games are chosen at random, what is the probability that exactly 4 of those games are won by the Colonials? Round your response to at least three decimal places. (If necessary, consult a list of formulas.) X 5 A binomial experiment with probability of success p=0.79 and n= 7 trials is conducted. What is the probability that the experiment results in 6 or more successes? Do not round your intermediate computations, and round your answer to three decimal places.

(b) Find the odds in favor of drawing a six.A sample of 409 people is selected. The people are classified according to place of residence ("urban", "suburban", or "rural"). They are also classified according to highest educational degree earned ("no college degree", "two-year degree", "four-year degree", or "advanced degree"). The results are given in the contingency table below. No college degree Two-year degree Four-year degree Advanced degree Urban 39 17 44 31 Suburban 47 36 34 40 Rural 28 20 49 24 What is the relative frequency of people in the sample whose place of residence is suburban? Round your answer to two decimal places. X ?A spinner with 10 equally sized slices has 4 yellow slices, 3 red slices, and 3 blue slices. Lashonda spun the dial 1000 times and got the following results. Answer the following. Round your answers to the nearest thousandths. (a) From Lashonda's results, compute the experimental probability of landing on red. I] (b) Assuming that the spinner is fair, compute the theoretical probability of landing on red. I] (c) Assuming that the spinner is fair, choose the statement below that is true. 0 The smaller the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability. 0 The experimental probability will never be very close to the theoretical probability, no matter the number of spins. O The larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability. Suppose X follows a binomial distribution with n=35 trials and probability of success p=0.68. (a) Find u y, the mean of X. Do not round your answer. X ?
