A) Two arthroscopic surgeries were compared among patients suffering from osteoarthritis who had at least moderate knee pain. The lavage type has the joint flushed with fluid and no instrument is used to remove tissue; the debridement type has the joint flushed with fluid and an instrument is used to remove tissue. Knee pain scores, ranging from 0 to 100 with higher scores indicating severe pain, were obtained for patients randomly assigned to the two groups after the surgery and the results are given below:

------------Sameple Size--------Sample Mean-------Sample Standard Deviation

Lavage 11 59 24

Debridment 13 49 23

Determine a 95% confidence interval for the difference between the mean knee pain score for the lavage group and that for the debridement group

NYC Limo has a client who will sign a lease for a limousine. Consider a $90,000 limousine that will last for four years and can be depreciated on a three-year MACRS schedule. Assume that lease rates for old and new limousine are the same and that Acme Limo Inc's pretax administrative costs are $9,000 per limousine per year (these costs will occur at the beginning of the year). The after-tax cost of capital is 8% and the tax rate is 20%. The limousine is expected to be sold for $15,000 at the end of 4 years. The Lease payments are made in advance, that is, at the start of each year. The inflation rate is zero. What is the break-even operating lease rate for the limousine?
