Consider a C corporation. The corporation earns $2 per share before taxes. After the corporation has paid its corresponding taxes, it will distribute 50% of its earnings to its shareholders as a dividend. The corporate tax rate is 35%, the tax rate on dividend income is 20%, and the personal income tax rate is set at 28%. What are the shareholder's earnings from the corporation after all corresponding taxes are paid?

A researcher randomly assigns five individuals to receive a new experimental procedure, measuring number of decision-making errors before and after the procedure. Baseline scores were 7, 6, 9, 7, and 6. Scores after the experimental treatment were. 5, 2, 4, 3, and 6. Conduct a two-tailed hypothesis test with α = .05, being sure to specify the null and alternative hypotheses.

An unmarked police car traveling a constant 85 km/h is passed by a speeder traveling 139 km/h . Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.40 m/s2 , how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)?
