10.5. Some studies have shown that in the United States, men spend more than women buying gifts and cards on Valentine's Day. Suppose a researcher wants to test this hypothesis by randomly
sampling 9 men and 10 women with comparable demographic characteristics from various large cities
across the United States to be in a study. Each study participant is asked to keep a log beginning one
month before Valentine's Day and record all purchases made for Valentine's Day during that one-
month period. The resulting data are shown below.
Men $107.48 143.61 90.19 125.53
Women $125.98 45.53 56.35 80.62
70.79 83

Using the critical value method and the above data, at 1% level of significance, determine if, on average,
men actually do spend significantly more than women on Valentine's Day. Assume that such spending
is normally distributed in the population and that the population variances are equal.

Shrieves casting company is considering adding a new line to its product mix, and the capital budgeting analysis is being conducted by sidney johnson, a recently graduated mba. the production line would be set up in unused space in the main plant. the machinery’s invoice price would be approximately $200,000, another $10,000 in shipping charges would be required, and it would cost an additional $30,000 to install the equipment. the machinery has an economic life of 4 years, and shrieves has obtained a special tax ruling that places the equipment in the macrs 3-year class. the machinery is expected to have a salvage value of $25,000 after 4 years of use. the new line would generate incremental sales of 1,250 units per year for 4 years at an incremental cost of $100 per unit in the first year, excluding depreciation. each unit can be sold for $200 in the first year. the sales price and cost are both expected to increase by 3% per year due to inflation. further, to handle the new line, the firm’s net working capital would have to increase by an amount equal to 12% of sales revenues. the firm’s tax rate is 40%, and its overall weighted average cost of capital, which is the risk-adjusted cost of capital for an average project (r), is 10%. define “incremental cash flow.” (1) should you subtract interest expense or dividends when calculating project cash flow?
