Air Pollutant Concentrations and Factors Affecting Air Pollution Air inversions greatly affect local air quality because pollution is trapped. Assume an inversion occurs over a 75 m x 50 m surface area and there is no way for the pollutant to escape. There are 100 cars and each one produces 10.5 µg/s of carbon monoxide (CO). Part a [1 points]: What is the concentration (in ppm) after 1 hour if the inversion is at 150. m? Part b [1 points]: What is the concentration (in ppm) after 1 hour if the inversion is at 1,500. m? Part c [1 point]: Is the NAAQS exceeded in either case? The 1-hr concentration for CO should not exceed 35 ppm. Part d [3 points]: Describe three ways (natural or human-caused) that the concentration of CO would decrease.

a. 500 mol/h methane at 40°C was fed to a furnace and burned with 15% of excess air at
80°C. The exit gas products comprise of CO2 and CO in mol ratio of 15 (CO2/CO), where
all methane was burned during the combustion. The product gas leaves the furnace at
380°C. Determine the amount of heat loss from the furnace in kW.

b. During the combustion process in part (a), the heat produced is used to heat up the water
to produce steam. By considering the changes of the following conditions for the same
process in part (a), predict the changes to the production rate of steam and justify your
answer:

A survey conducted by the American Automobile Association showed that a family of four spends an average of $215:60 per day while on vacation. Suppose a sample of 64 families of four vacationing at Niagara Falls resulted in a sample mean of $252:45 per day and a sample standard deviation of $74:50. Using a 98% confidence interval estimate, you wish to determine whether the average amount a family of four will spend when vacationing at Niagara Falls per day is different from the average amount for a family of four claimed by the American Automobile Association.

a) If the amount spent by a family of four while vacationing at Niagara Falls is skewed to the right, would you expect the median amount spent to be greater than or less than $252:45? Explain.

b) Is it necessary to assume a normal distribution on the population to estimate the value of the mean spending per day? Explain.

c) What is the sampling distribution of the sample statistic when you construct a 98% confidence interval? Explain in detail.

d) Construct a 98% confidence interval estimate of the population mean amount of a family of four when vacationing at Niagara Falls per day and interpret the interval.

e) Based on result in part d), does it appear that the population mean amount spent per day by families visiting Niagara Fall differs the mean amount per day for a family of four reported by the American Automobile Association? Explain.

THANKSGIVING SPECIAL!!! For this applied assignment we will be looking at the number of turkeys and bottles of wine sold each November, comparing the American northeast (i.e., our sample) to the total American averages (i.e., the population).

Every Thanksgiving, an average of 960,000 turkeys and 90,000 bottles of wine are sold per state. Importantly, the population variance/standard deviation is not known. Below is the number of turkeys and bottles of wine sold in each of the ten northeast states.

1. What is the strength and direction of the relationship between the number of turkeys and bottles of wine sold in the American northwest?
2. What is r-crit and r-obt for the hypothesis test stated in question #1? Is the hypothesis test significant or insignificant? Would you reject or fail to reject the null hypothesis assuming an alpha-level of 0.05?
3. If you were to use this relationship (and linear regression) to predict how many bottles of wine will be sold in a northeast state in 2018 given the number of turkeys sold in that state, how much more accurate would you be (in percent) compared to if you did not use the relationship to make this prediction (round to two decimal places)?

In Re Boardwalk Marketplace    688 F. Supp 115 US District Court, Connecticut, 1987

Investors purchased interests in limited partnerships that were organized to redevelop property in Atlantic City. To finance their purchases, the investors executed promissory notes payable to American Funding Limited. The notes stated, in part:

            I will pay __ monthly installments of principal and interest, each in the amount of $________, commencing on the ____ day of _________ (estimated first payment date). Lender will notify me in writing of the first payment due date, the amount of the first payment, the date of the first payment, the date of the final payment and the amount of the final payment.

In the blanks, someone had handwritten figures representing the number of monthly payments, the amount of each payment, and an estimated date on which the payments were to begin. American Funding Limited sold these notes to various banks. When the redevelopment plan collapsed, many of the investors ceased making payments on their notes. The investors asserted that the notes were non-negotiable because the payment date was not definite. The banks argued that, whether or not the payment date was definite, equity demanded that the notes be treated as if they were negotiable so that the banks, which were innocent of all wrongdoing, could collect the money owed them. If the notes were non-negotiable, the banks’ right to collect might be defeated by claims the investors had against American Funding.

Did these notes comply with UCC requirements for negotiability? If not, should the notes be treated as if they were negotiable?

Relay Health is a company that has operated in the health care environment for several years. This organization has developed a platform whereby patients are able to communicate with their doctors online for consultations (www.relayhealth.com). The adoption of this service has been slowly growing for many years but has not received widespread acceptance in the marketplace by physician groups, although there are many benefits that can be discerned from the platform for patients or employers who might have employees who have doctors who are on such a platform. And, insurers such as Blue Cross and Cigna have also begun to accept that online visits are acceptable and are moving increasingly to reimbursing this approach. In spite of this growing trend, less than 3% of the family physicians in the American Academy of Family Practice report doing e-visits.

Recently, a company called Sophrona Solutions (https://sophrona.com/) has developed a platform that initially was for ophthalmology practices. One of the larger developers is American Well (https://amwell.com/cm/?test=true&gclid=CI7Zw4Xdp8oCFUUTHwodqssEhw), the producer of online care. They have announced that they are expanding their online portal nationally.

The CEO of Relay Health has called you in as a consultant to analyze this rapidly changing market.

There are several growth strategy alternatives available. Explain each alternative and then consider/apply each alternative for Relay Health. Which one did American Well employ? Which alternatives might be available to Relay Health? How might they be implemented?

Airbus sold an A400 aircraft to Delta Airlines, a U.S. company, and billed $30 million pay- able in six months. Airbus is concerned about the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.05/€ and the six-month forward exchange rate is $1.10/€. Airbus can buy a six-month put option on U.S. dollars with a strike price of €0.95/$ for a premium of €0.02 per U.S. dollar. Currently, six- month interest rate is 2.5 percent in the euro zone and 3.0 percent in the United States. a. Should a firm hedge? Why or why not? b. Compute the guaranteed euro proceeds from the American sale if Airbus decides to hedge using a forward contract. c. If Airbus decides to hedge using money market instruments, what action does Airbus need to take? What would be the guaranteed euro proceeds from the American sale in this case? d. If Airbus decides to hedge using put options on U.S. dollars, what would be the “expected” euro proceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate. e. At what future spot exchange do you think Airbus will be indifferent between the option and money market hedge?

Wallace & Wallace, CPAs, audited the financial statements of West Co., a nonpublic entity, for the year ended September 30, 20X1, and expressed an unqualified opinion. For the year ended September 30, 20X2, West issued comparative financial statements. Wallace & Wallace reviewed West's 20X2 financial statements and Gordon, an assistant on the engagement, drafted the accountant's review report below. Martin, the engagement supervisor, decided not to reissue the prior year's auditor's report, but instructed Gordon to include a separate paragraph in the current year's review report describing the responsibility assumed for the prior year's audited financial statements.

Martin reviewed Gordon's draft and indicated in Martin's Review Notes that there were many deficiencies in Gordon's draft. Accountant's Review Report

We have reviewed the accompanying balance sheet of West Company as of September 30, 20X2, and the related statements of income and cash flows for the year then ended.

A review includes primarily applying analytical procedures to management's financial data and making inquiries of company management. A review also includes assessing the accounting principles used and significant estimates made by management, as well as, evaluating the overall financial statement presentation. Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America. Our responsibility is to conduct the review in accordance with standards issued by the American Institute of Certified Public Accountants. Those standards require us to perform procedures to obtain limited assurance that there are no material modifications that should be made to the financial statements. We believe that the results of our procedures provide a reasonable basis for our report. Based on our review, we are not aware of any material modifications that should be made to the accompanying financial statements. Accordingly, the accompanying financial statements have been prepared assuming that the company will continue as a going concern. Furthermore, we have no responsibility to update this report for events and circumstances occurring after the date of this report. The financial statements for the year ended September 30, 20X1, were audited by us and we expressed an unqualified opinion on them in our report dated November 7, 20X1, but we have not performed any auditing procedures since that date. In our opinion, the financial statements referred to above are presented fairly, in all material respects, for the year then ended in conformity with generally accepted accounting principles.
