The Neal Company wants to estimate next year's return on equity $($ROE$)$ under different financial leverage ratios. Neal's total capital is $$12$ million, it currently uses only common equity, it has no future plans to use preferred stock in its capital structure, and its federal$-$plus$-$state tax rate is $40\%.$ The CFO has estimated next year's EBIT for three possible states of the world: $$4\mathrm{.}5$ million with a $0\mathrm{.}2$ probability, $$3\mathrm{.}4$ million with a $0\mathrm{.}5$ probability, and $$0\mathrm{.}9$ million with a $0\mathrm{.}3$ probability. Calculate Neal's expected ROE, standard deviation, and coefficient of variation for each of the following debt$-$to$-$capital ratios. Do not round intermediate calculations. Round your answers to two decimal places at the end of the calculations.
