Hospital personnel routinely examine patient records for error, such as incomplete insurance information, on incomplete patient history, or missing/incomplete medical records. On average, about 270 new patients are admitted each day. Historically, about 8% of these records have contained errors. If a random sample of 40 new patient records is checked each day, what is the probability that this sample will contain at least two patient record with missing information?

A car accident expert is assigned to a case where the insurance company suspects the car company to use lower quality steel (lower TS) than the standards in their bumpers. The expert is given a post-crash bumper to run his test on. Since the bumper is completely deformed, he cannot place it into the normal bumper tensile tester. He is thinking about running a hardness test on the deformed bumper to estimate the TS of the steel to test the insurance company's theory. Do you think his method is acceptable? why?

A parabolic trough concentrator with width of 3 m and length of 25 m has an absorbed solar radiation per unit area of aperture (S) of 600 W/m2. The receiver is a cylinder with an emittance of 0.3 and is surrounded by an evaluated glass cylindrical envelope. The absorber has a diameter of 50 mm and the transparent envelope has an outer diameter of 100 mm with a thickness of 5 mm. The collector is designed to heat a fluid entering the absorber at 100oC at a flow rate of 0.0425 kg/s. The fluid has a specific heat of 3.89 kJ/kg K. The heat transfer co-efficient inside the tube is 250 W/m2 K and the overall loss co- efficient of 5 W/m2 K. The tube is made up of stainless steel with a thermal conductivity 1 of 15 W/m K and a wall thickness of 4 mm. Assume that the product of τcovαabs for the parabolic receiver is τcovαabs ~ 1.0 and the ambient temperature is 20oC. Determine the following: (a) the useful heat gain from the collector; (b) PTC collector efficiency; (c) the exit heat transfer fluid temperature; (d) the mass flow of the heat transfer fluid to achieve the same exit temperature (calculated in c) for the parabolic trough collector with a F_R value of 0.70.

Western Manufacturing is involved with several potential contingent liabilities
Western Manufacturing is involved with several potential contingent liabilities. Your assignment is to draft the appropriate accounting treatment for each situation described below. Western’s fiscal year-end is December 31, 2021, and the financial statements will be issued in early February 2022.
a. During 2021, Western experienced labor disputes at three of its plants. Management hopes an agreement will soon be reached. However, negotiations between the company and the unions have not produced an acceptable settlement, and employee strikes are currently under way. It is virtually certain that material costs will be incurred, but the amount of possible costs cannot be reasonably estimated.
b. Western warrants most products it sells against defects in materials and workmanship for a period of a year. Based on its experience with previous product introductions, warranty costs are expected to approximate 2% of sales. A new product introduced in 2021 had sales of $2 million, and actual warranty expenditures incurred so far on the product are $25,000. The only entry made so far relating to warranties on this new product was to debit Warranty Expense $25,000 and credit Cash $25,000.
c. Western is involved in a suit filed in January 2022 by Crump Holdings seeking $88 million, as an adjustment to the purchase price in connection with the company’s sale of its textile business in 2021. The suit alleges that Western misstated the assets and liabilities used to calculate the purchase price for the textile division. Legal counsel advises that it is reasonably possible that Western could lose up to $88 million.
Required:
In a memo, describe the appropriate means of reporting each situation and explain your reasoning.
