Question asap Problems 1. Jesse, Matthew, and Jonathan have been appointed to serve on the decision committee for the fourth grade class. They will decide the field trip plans for the fourth grade this year. Choice Jesse Preferences Matthew Jonathan First с B А Choice A - low cost trip to visit city goverment office Choice B - medium cost trip to visit county government office Choice C - high cost trip to visit state government office Second А с B Third B A C What is the outcome of majority voting? Assuming individual's preferences obey transitivity, will that be true of the majority vote? Explain. Thelma and Louise are neighbors. During the winter, it is impossible for a snowplow to clear the street in front of Thelma's house without clearing the front of Louise's. Thelma's marginal benefit from snowplowing services is 50 - 52, where Z is the number of times the street is plowed. Louise's marginal benefit is 30 - 32. The constant) marginal cost of getting the street plowed is $32. Sketch the aggregate marginal benefit curve and the marginal cost curve, calculate the efficient number of plows, and identify the efficient point in your graph. Aggregate MB

It's Halloween, and Ralphie has 6 large bags, each filled with a combination of 4 different kinds of candy. Each bag should have an approximately equal amounts of each flavor. But, being a buffalo, Ralphie is not sure that she spread the candy out evenly. She has asked your help to determine whether the proportions of flavors within each bag is the same. Each bag contains hundreds of pieces of candy, so we can't count them all by hand. Instead, you take a sample of 50 pieces from each bag. The table below displays the counts of each type of candy within each sample of 50 pieces: Candy A Candy B Candy C Candy D Bag 1 14 18 11 6 Bag 2 10 20 12 9 Bag 3 13 14 15 8 Bag 4 15 15 10 10 Bag 5 11 17 13 9 Bag 6 11 14 14 11 Part B) Determine whether the proportions of candy are equal by solving for the p-value of the appropriate test. Save your answer as p2.b. Round your answer to three decimal places. # your code here p2.b = NA Part E) After some thinking, Ralphie has changed her mind and believes that the candies actually follow the below proportions: PA = 0.25 PB = 0.35 Pc = 0.25 PD = 0.25 At a significance level of a = 0.05, determine if your observed samples agree with Ralphie's newly proposed proportions. Save the p-value of your calculations as p2.e.pval. Round this answer to three decimal places. Into variable p2.e, save TRUE if your data does agree with the new proportions, or FALSE if it does not. # your code here p2.e = NA p2.e.pval = NA
