A pizza shop advertises that they deliver in 30 minutes or less or it is free. people who live in homes that are located on the opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza. write the null and alternative hypotheses that can be used to conduct a significance test.

Evaluate a real situation between two economic actors; it could be any scenario: two competing businesses, two countries in negotiations, two kids trading baseball cards, you and another person involved in an exchange or anything else. use game theory to analyze the situation and the outcome (or potential outcome). be sure to explain the incentives, benefits and risks each face.

Adamson company manufactures four lines of garden tools. as a result of an activity analysis, the accounting department has identified eight activity cost pools. each of the product lines is produced in large batches, with the whole plant devoted to one product at a time. classify each of the following activities or costs as either unit-level, batch-level, product-level, or facility-level. activities (a) machining parts. (b) product design. (c) plant maintenance. (d) machine setup. (e) assembling parts. (f) purchasing raw materials. (g) property taxes. (h) painting.

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
