The manager of Golden Ray Corporation receives a bonus if company profits exceed $1,000,000 this year. During the final week of the year, the manager changes an accounting policy that will increase reported profits from $950,000 to $1,025,000, triggering his bonus. The change in profits of $75,000 will reverse itself in the next year, and the accounting change has no impact on Golden Ray's cash flow. Discuss the above situation as it relates to both an agency problem and efficient markets. (Please write between 300-500 words)

In a test of the effectiveness of garlic for lowering​ cholesterol,

45

subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes

​(beforeminus−​after)

in their levels of LDL cholesterol​ (in mg/dL) have a mean of

5.2

and a standard deviation of

15.8.

Construct a 95​%

confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL​ cholesterol?
