Math SAT scores (Y) are normally distributed with a mean of 1500 and a standard deviation of 140. An evening school advertises that it can improve students' scores by roughly a third of a standard deviation, or 30 points, if they attend a course which runs over several weeks. (A similar claim is made for attending a verbal SAT course.) The statistician for a consumer protection agency suspects that the courses are not effective. She views the situation as follows: H0 : = 1500 vs. H1 : = 1460.
Assume that after graduating from the course, the 420 participants take the SAT test and score an average of 1450. Is this convincing evidence that the school has fallen short of its claim at 2.5% level?

Your friend, another accountant, has bet you that with your knowledge of accounting and just the computations for common analytical measures, you can figure out many aspects of a company's financial statements. You take the bet!
Match each computation to one of the liquidity and solvency measures in the table. (Hint: Begin by looking for simple computations and identifying the amounts in those computations. Look for other measures that use those amounts.)
| Liquidity and Solvency Measures | Computations |
| Working capital | $3,093,000 – $840,000 |
| Accounts receivable turnover | ($983,100 + $127,000) ÷ $127,000 |

| Current ratio | $2,530,000 ÷ $4,077,000 |
| Inventory turnover | $3,093,000 ÷ $840,000 |
| Times interest earned | [($1,072,000 + $1,100,000) ÷ 2] ÷ ($4,100,000 ÷ 365) |
| Number of days' sales in receivables | $2,690,000 ÷ $1,690,000 |
| Ratio of liabilities to stockholders' equity | $8,270,000 ÷ [($714,000 + $740,000) ÷ 2] |
| Number of days' sales in inventory | $4,100,000 ÷ [($1,072,000 + $1,100,000) ÷ 2] |

Look for patterns in the computations and match them to ratios that are related to each other. Identify the amounts in the computations and consider how they are related to amounts in other computations.
Balance Sheet
Shaded cells have feedback.
Use the following balance sheet form to enter amounts you identify from the computations on the Liquidity and Solvency Measures panel. You will identify other amounts for the balance sheet on the Profitability Measures panel. If you have a choice of two amounts, assume the first amount in the ratio is for the end of the year. Compute any missing amounts.

Use the following comparative income statement form to enter amounts you identify from the computations on the Liquidity and Solvency Measures panel and on the Profitability Measures panel. Compute any missing amounts and complete the horizontal analysis columns. Enter percentages as decimal amounts, rounded to one decimal place. When rounding, look only at the figure to the right of one decimal place. If < 5, round down and if ? 5, round up. For example, for 32.048% enter 32.0%. For 32.058% enter 32.1%.

Your accountant friend reveals that the company whose information you have been working on is actually a company he is thinking of investing in. What advice and insight do you have for your friend?
Using only the information from your horizontal analysis of the comparative income statement, complete the following sentences.
Net income has decreased significantly from 20Y5 to 20Y6, even though cost of goods sold has increased. However, cost of goods sold has also not changed , which slowed the increase in interest expense . In addition, interest expense has increased at a faster rate. The company appears to be taking the right steps .
Points:
2 / 7
Based on these observations, do you recommend that your friend invest in this company’s stock? Yes

CURRENT YIELD, CAPITAL GAINS YIELD, AND YIELD TO MATURITY Hooper Printing Inc. has bonds outstanding with 9 years left to maturity. The bonds have an 8% annual coupon rate and were issued 1 year ago at their par value of $1,000. However, due to changes in interest rates, the bond’s market price has fallen to $901 40. The capital gains yield last year was −9 86%.
A. What is the yield to maturity?
B. For the coming year, what are the expected current
and capital gains yields? (Hint:
Refer to footnote 7 for the definition of the current yield and to
Table 7.1.)
C. Will the actual realized yields be equal to the
expected yields if interest rates change? If
not, how will they differ?

The invasive diatom species Didymosphenia geminata has the potential to inflict substantial ecological and economic damage in rivers. An article described an investigation of colonization behavior. One aspect of particular interest was whether y = colony density was related to x = rock surface area. The article contained a scatterplot and summary of a regression analysis. Here is representative data.
