Altmans z-score Altmans z-score is a financial tool for predicting insolvency in a business. For a certain company, the z-score formula is z=0.84+0.6StockpriceOutstandingsharesTotalliabilty In this exercise, we assume that thre are 45, 000 outstanding shares at a price of 4.80 each. a. Use L, for total liability, in dollard, and give a formula for the z-score for this company. b. Would a larger total liability idicate a better or worese outlook for the company? c. A z-score of 1.81 or lower indicates a high probability of insolvency. What is the smallest value of L that will give a z-score that indicates a high probability on insolvency?
Define Newton’s Law of Cooling. Then name at least three real-world situations where Newton’s Law of Cooling would be applied.
2.21 The manufacturing company in Problem 2.20 also produces electric insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing in high-powered labs is carried out to determine how much force is required to break the insulators. Force is mea- sured by observing how many pounds must be applied to the insu- lator before it breaks. The force measurements, collected from a sample of 30 insulators and stored in Force , are:1,870 1,728 1,656 1,610 1,634 1,784 1,592 1,662 1,866 1,764 1,734 1,662 1,550 1,756 1,762 1,866 1,820 1,744 1,810 1,752 1,680 1,810 1,652 1,7361,522 1,696 1,734 1,774 1,788 1,688a.

To see the effect of a relatively small error in the estimate of the amount of carbon-14 in a sample being dated, consider this hypothetical situation: a. A bone fragment found in central Illinois in the year 2000 contains 17% of its original carbon-14 content. Estimate the year the animal died. b. Repeat part (a), assuming 18% instead of 17%. c. Repeat part (a), assuming 16% instead of 17.

You are interested in determining which of two brands of light bulbs, brand A and brand B, lasts longer under differing conditions of use. Fifty Bovano lamps are fitted with brand A light bulbs, and 50 Bulbrite lamps are fitted with brand B light bulbs. Each light bulb is left on for 20,000 hours straight. Light bulb life is then measured for each bulb, and the average light bulb life for the two brands is compared. What is wrong with this experimental design? Nothing is wrong with this design. The type of lamp is a confounding variable. Not enough light bulbs of each type are used in the study. The experiment should have been conducted on more than two brands of lamps.
In a certain suburb of Montréal, residents have expressed their worries about the quality of the air. Of particular concern is the concentration (in μg/m3) of particulate matter smaller than 2.5 μm in size (PM2.5). The environmental standard is a PM2.5 concentration of 15 μg/m3 or less. 9-a) To conduct this study, Thomas installs 25 PM2.5 detectors at different locations in the suburban area. Each detector will provide one reading of PM2.5 concentration at a given time. With 25 detectors, what is the probability that Thomas declares the sample mean of PM2.5 concentrations significantly greater than the environmental standard while the population mean is 16 μg/m3? The population variance is assumed to be known and equal to 9. Use α = 0.01. 9-b) Thomas is interested to purchase a new and cheaper instrument to measure PM2.5 concentration. He is worried, however, that the precision of the new instrument may be lower than that of the current one. To be acceptable, the standard…
1. A cement grinding mill “A” with a capacity of 50 tons/hr utilizes forged steel grinding balls costing P12,000/ton, which have a wear rate of 100 grams/ton cement milled. Another cement mill “B” of the same capacity uses high chrome steel grinding balls costing P50,000/ton with wear rate of 20 grams/ton cement milled. Determine the more economical grinding mill, considering other factors to be the same.
