Its EBIT was $12.6 million, and its tax rate was 40%. What was its interest expense? [Hint: Write out the headings for an income statement, and then fill in the known values. Then divide $6 million of net income by (1 - T) = 0.6 to find the pretax income. The difference between EBIT and taxable income must be interest expense. Use this same procedure to complete similar problems.] Write out your answer completely. For example, 25 million should be entered as 25,000,000.

Fire is a particular threat to shrubs in dry climates, as it can injure the roots as well as destroy the aboveground material. One study of resprouting took place in a dry area of Mexico. The investigation clipped the tops of samples of several species of shrubs. In some cases, they also applied a propane torch to the stumps to simulate a fire. Of 19 specimens of a particular species, 6 resprouted after fire. Estimate with 96% confidence the proportion of all shrubs of this species that will resprout after fire.
