The Acton-Boxborough School District will issue a 30-year bond with a face value of $ 5,000,000 to construct a new building for the district’s junior high school. The bond has a stated annual interest (coupon rate) of 5 percent, and the district will make interest (coupon) payments based on the stated interest rate twice a year.

a) What is the semiannual interest (coupon) payment? (semiannual = every six months)

b) How much will the school district receive from the bond offering under the following conditions:

a. Market interest rates increase to 8% at the time of the offering. (Assuming interests are compounded semiannually).

b. Market interest rates decrease to 5% at the time of offering. (Assuming interests are compounded semiannually).

As part of his contract at his new job, Jim is provided a company car and gas card to go back and forth to work. He sometimes uses the car for out-of-town travel approximately once a month. Jim also uses the car and the gas card for his family vacations, dinner, etc. Explain the applicable tax law regarding employee compensation and the criteria for deducting expenses. Make at least two recommendations for ways that Jim can ensure that he is compliant with the tax law.

1. During the spring of 1999, many fuel storage facilities in Serbia were destroyed by bombing. As a result, significant quantities of oil products were spilled and burned, resulting in soil pollution. An article reports measurements of heavy metal concentrations at several industrial sites in June 1999, just after the bombing, and again in March of 2000. At the Smederevo site, on the banks of the Danube River, eight soil specimens taken in 1999 had an average lead concentration (in mg/kg) of 10.7 with a standard deviation of 3.3. Fifteen specimens taken in 2000 had an average lead concentration of 33.8 with a standard deviation of 0.50. Let μXμX represent the population mean for the year 2000 and let μYμY represent the population mean for the year 1999. Find a 95% confidence interval for the difference μX−μYμX−μY. Round down the degrees of freedom to the nearest integer and round the answers to three decimal places.

The 95% confidence interval is (, ).

2. In a survey of 500 residents in a certain town, 272 said they were opposed to constructing a new shopping mall. Can you conclude that more than half of the residents in this town are opposed to constructing a new shopping mall? Find the P-value and state a conclusion. Round the answer to four decimal places.

The P-value is_.

The data presented in worksheet 4 is the results of a 4-year study conducted to assess how age, weight, and gender influence the risk of diabetes. Risk is interpreted as the probability (times 100) that the patient will have diabetes over the next 4-year period.

a) What predictive model you suggest to relate risk of diabetes to the person’s age, weight and the gender. Why? b)Develop an estimated multiple regression model that relates risk of diabetes to the person’s age, weight, gender and life style. Present the regression formula as a mathematical equation. Interpret the coefficients of the regression and comment on the strength of the regression.

c) What is the risk percentage of diabetes over the next 4 years for a 52-year-old woman living in a small town with 80 kg weight?

This week, we learned how we form and store memories, how we process information cognitively, and how motivation guides our behavior. With all this new knowledge, what suggestions would you give to a student who is experiencing "spring fever" and is having difficulty concentrating on school work and does not seem to have the motivation to do the work during the remainder of the school year? Be as creative as you would like. For this discussion, you may create a brochure or Powerpoint presentation.

Exercise 1                                                                                                                                                                                    

Prepare journal entries to record the following transactions for Riyadhtown for 2018. The Town records encumbrances only for its Supplies appropriation.

            a.    Riyadhtownadopted the following budget for the year:

                        Revenues:

                              Property taxes                                                        SAR 375,000

                              Licenses and fees                                                              35,000

                        Appropriations:

Salaries                                                                            255,000

                              Supplies                                                                             40,000

                              Interest                                                                                1,500

            b.   Property tax bills amounting to SAR375,000 were sent to the property owners.

            c.    Because property taxes were not due to be received for several months and the town needed cash to finance its activities, Riyadhtown borrowed SAR 100,000 from a local bank using tax anticipation notes.

            d.   Riyadhtownpaid salaries in the amount of SAR 95,000.

            e.    The town sent out two purchase orders for supplies: purchase order A for SAR6,000 and purchase order B for SAR5,000.

            f.    The town received SAR 130,000 from property owners in payment of their property taxes.

            g.   Riyadhtownrepaid the bank on its borrowing in transaction c. The amount paid was SAR101,000, which included interest of SAR1,000.

            h.   The town collected SAR 25,000 for fishing licenses.

            i.    The town received the supplies ordered on purchase order A in transaction e. All the supplies arrived in good condition and the invoice for SAR 6,300 was approved for payment.

1. Suppose the annual incidence of asthma in the general population among children 0-4 years of age is 1.4% for boys.

   1. If 10 cases are observed over one year among 500 boys 0-4 years of age with smoking mothers, then test if there is a significant difference in asthma incidence between this group and the general population. [6]

      1. STEP 1: STATE THE APPROPRIATE NULL AND ALTERNATIVE HYPOTHESES

      2. STEP 2: DEFINE THE CRITICAL REGION

      3. STEP 3: COMPUTE THE APPROPRIATE TEST STATISTIC

      4. STEP 4: STATE YOUR STATISTICAL DECISION

      5. STEP 5: STATE YOUR PRACTICAL CONCLUSION

      6. STEP 6: REPORT THE P-VALUE

2. 2. Construct and practically interpret a 95% CI for the true incidence rate of asthma in this group. [8]

Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim (Don’t just say Reject the null hypothesis or fail to reject the null hypothesis).

5. A simple random sample of 15-year old boys from one city is obtained and their weights (in pounds) are listed below. Use a 0.01 significance level to test the claim that these sample weights come from a population with a mean equal to 147 lb. Assume that the standard deviation of the weights of all 15-year old boys in the city is known to be 16.7 lb.
