On a game show, a contestant is given the digits 3, 4, and 5 to arrange in the proper order to form the price of an appliance. If the contestant is correct, he or she wins the appliance. What is the probability of winning when the contestant knows that the price is at least $400?
Question 5 According to a survey of American households, the probability that the residents own 2 cars if annual household income is over $25,000 is 80%. Of the households surveyed, 60% had incomes over $25,000 and 70% had 2 cars. Use the Bayes Theorem to calculate the probability that annual household income is at most $25,000 if the residents of a household do not own 2 cars.
A dart, thrown at random, hits a square target. Assuming that any two parts of the target of equal area are equally likely to be hit, find the probability that the point hit is nearer to the center than to any edge. Write your answer in the form (a√b + c)/d, where a, b, c, and d are integers.
To a study the effectiveness of an interactive e-book, aresearcher gave 20 students a pre-test, had them studyfrom the e-book, and then gave them a post-test. Thetable below summarizes the data she collected.The researcher conducted a hypothesis test to see if usingthe e book would produce a significant increase in meanscore.

Question 40 In 2008, 46% of business owners gave a holiday gift to their employees. A 2009 survey of business owners indicated that 35% plan to provide a holiday gift to their employees (Radio, WEZV, Myrtle Beach, South Carolina,) Suppose the survey results are based on a sample of 60 business owners. Part A How many business owners in the survey plan to provide a holiday gift to their employees? Ans. Part B Suppose the business owners in the sample do as they plan. Compute the p-value for a hypothesis test that can be sued to determine if the proportion of business owners providing holiday gifts has decreased from the 2008 level. Part C Using a 0.05 level of…
A psychologist examining art appreciation selected an abstract painting that had no obvious top or bottom. Hangers were placed on the painting so that it could be hung with any one of the four sides at the top. The painting was shown to a sample of n = 50 participants, and each was asked to hang the painting in the orientation that looked correct. The following data indicate how many people chose each of the four sides to be placed at the top. Are any of the orientations selected more (or less) often than would be expected simply by chance? Test with a = .05. Top Up (correct) Bottom up Left side up Right side up 18 17 7 8
