1. Assume that you held a Treasury note that makes coupon payments on May 15 and November 15. The number of days between each coupon payment is 184. Suppose you sold the bond on June 27, 2016. If the number of days between May 15 and June 27 is 43, the bond carried a coupon rate of 3.875% and matures as of May 15, 2026 ($1,000 par value),
a) What would have been the settlement (dirty) price on June 27, 2016 if the bond was priced to yield 4.0369%?
b) What was the accrued interest?
c) What was the market price (quoted on the Wall Street Journal)?

To study how social media may influence the products consumers buy, researchers collected the opening weekend box office revenue (in millions of dollars) for 23 recent movies and the social media message rate(average number of messages referring to the movie per hour). The data are available below. Conduct a complete simple linear regression analysis of the relationship between revenue (y) and message rate (x).

The least squares regression equation is y=−0.031+l0.086x. (Round to three decimal places as needed.)
Check the usefulness of the hypothesized model. What are the hypotheses to test?
A.H0: β1≠0 against Ha:β1=0
B.H0β0:=0 againstHa:β0≠0
C.H0:β0≠0 against Ha:β0=0
D.H0:β1=0 againstHa:β1≠0 Your answer is correct.
Determine the estimate of the standard deviation.
s=9.59 (Round to two decimal places as needed.)
What is the test statistic for the hypotheses?
t=15.14 (Round to two decimal places as needed.)
What is the p-value for the test statistic?
p-value=0(Round to three decimal places as needed.)State the conclusion at α=0.05.
Since the p-value is less than α, there is sufficient evidence to reject H0.
Conclude there is
a linear relationship between revenue and message rate.What is the value for the coefficient of determination
r2?
r2=0.92 (Round to two decimal places as needed.)Interpret the value of r2 in the context of this problem.
A.r2 is the proportion of the total sample variability around message rate that is explained by the linear relationship between the revenue and the message rate.
B.r2 is the proportion of the sample points that do not fit within the 95% confidence interval.
C. r2 is the proportion of the sample points that fit on the estimated linear regression line.
D.r2 is the proportion of the total sample variability around mean revenue that is explained by the linear relationship between the revenue and the message rate.

Your manufacturing facility produces three styles of coffee tables for its customers. All three of the tables use the same Baltic birch plywood oval and then are treated differently to create the final products. The Waltons model has a natural wood finish and wooden legs. The jetsons model has aluminum sheet laminated to the wood base and aluminum legs. The Miami vice model has hot pink finish applied and black iron legs. The plywood ovals are manufactured in a process environment. Then, they are transferred to the next department where they undergo transformation into the finished products. The second department is a job-order cost environment.
Using the data on this page, prepare the process cost summary on the blank form provided. Then, using your answer from the process cost summary and other information provided, complete the job-order cost report by computing manufacturing cost per unit for each of the three models. Please not that the job order cost report is not complete – you’ll need to add some lines to arrive at your final manufacturing costs per unit.
