Dr. dow jones wants to know whether a problem-based approach to teaching economics will result in higher academic performance than his traditional method. of the six sections of economics 101 at his university, dr. jones randomly assigns three sections to the traditional method and three sections to the problem-based method for unit 1 of the course. then all sections switch the instructional method for unit 2. he plans to compare the performance of the two groups of sections on their unit 1 and unit 2 exams. this study employs a design.

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

Faldo corp sells on terms that allow customers 45 days to pay for merchandise. its sales last year were $325,000, and its year-end receivables were $60,000. if its dso is less than the 45-day credit period, then customers are paying on time. otherwise, they are paying late. by how much are customers paying early or late? base your answer on this equation: dso - credit period = days early or late, and use a 365-day year when calculating the dso. a positive answer indicates late payments, while a negative answer indicates early payments. a. 21.27b. 22.38c. 23.50d. 24.68e. 25.91b
