Test whether profit for Massive Dynamic increased across the two time periods. You are not told anything about the population variances. Highlight the numbers that help you test the null hypothesis. In the text box below, explain whether once company has outperformed the other based on the evidence you provided in the last four spreadsheets. You need to reference the numbers you highlighted in your analysis. If you are concise, this should only take a few sentences. Note that I have not provided an α, so your analaysis should include a discussion about significance levels.

Determine the optimal dynamic allocation of a nonrenewable resource across two time periods based on the information provided. Your answer should include: MNB1 MNB2 PV(MNB2) The optimal quantity of consumption in period one The optimal quantity of consumption in period two, and a detailed presentation of HOW you derived your answers. Period One Period Two Demand schedules: PD1 = 100 - 0.4Q1 PD2 = 160 - 0.5Q2 Supply schedules: PS1 = 20 + 0.2Q1 PS2 =...

Assume that you are told that because of some changes, the equilibrium price increased but it is unknown if the equilibrium quantity increased, remained the same, or decreased. Which of the following would be consistent with this outcome? a. There was a decrease in input costs and consumers expected lower income. b. Consumers expected a lower price and firms expected a higher price. c. There was a decrease in income (the good is inferior) and a decrease in the number...

Consider a firm that exists in a world with two periods (time 0 and time 1) and two equally likely states of the world at time 1. At time 0 the firm’s securities are traded. At time 1 the state is revealed. In the up-state the firm’s assets are worth $120 and in the down-state they are worth $40. The firm has debt outstanding with a face value of $60. Assume that the required rate of return is zero and...

You would like to see whether providing extra time to students on their test allows for them to achieve a higher grade. In the past, the average mark on this test is 68 percent. You select 25 students from your current class, who were given extra time on the test and see their average grade was 72 minutes (St Dev = 8). What is the appropriate hypothesis test? Why this is the correct test? What is the effect size?

11.2a A substance abuse researcher wants to know whether reaction time is increased by frequent alcohol use. He randomly selects 92 alcoholics and finds that their mean reaction time (in ms) equals 439.1. Reaction times to the stimulus in the general population are distributed normally with a mean equal to 445 and a standard deviation equal to 58.5 . Is there sufficient evidence to conclude that reaction times of alcoholics are higher than those of the general population? Use a...
