Is the transportation mode used to ship goods independent of type of industry? Suppose the following contingency table represents frequency counts of types of transporation used by the publishing and the computer hardware industries. Analyze the data by using the chi-square test of independence to determine whether type of industry is independent of transportation mode.Use a 5% level of significance. Publishing Data is Air- 32,  Train Data is 12, and Truck Data is 41. Computer Hardware Data is Air 5, Train Data is 6, and Truck Data is 24

A study was performed to examine whether the type of gasoline used is independent of a person's living status. The researcher surveyed 600 people and asked two questions. The first question asked was “Do you use regular, plus, or super gasoline when filling up?” The second question asked was “Do you rent or own your place of residence?” The results are shown below. Assume the significance level α = .05 is used for the test. Type of Gas Living Status...

Independent trucking (i.e. large semi trucks) is an industry that can be considered perfectly competitive. Suppose that U.S. manufacturers produce less output. What impact will this have on the independent trucking industry in the short run, in terms of the market price, output of an individual firm, and market equilibrium quantity? Explain your reasoning. What impact will the increase in manufacturing output have in the long run? Explain your reasoning.
