[16 points on Gradescope] Suppose that Y1,…,Yn{“version”:”1.1″,”math”:”Y1,…,Yn”} denote a random sample from an exponentially distributed population with mean θ{“version”:”1.1″,”math”:”θ”}. Find the MLE of the population variance θ2{“version”:”1.1″,”math”:”θ2″}. SHOW ALL YOUR WORK HINT: Remember that exponential distribution is f ( x ; θ ) = 1 θ e − x / θ , x > 0 , θ > 0

[16 points on Gradescope] The UA administration claims that on average undergraduates spend 22.1 hours per week studying. We want to test if this is accurate. We sample 213 students and find that the average of the time/per week they spend studying is 22.9 hrs/week with a samplestandard deviation of 7.2 hrs/week. a. State the null and alternative hypotheses and define the test statistic to be used. You should define any parameters you introduce. b. Suppose that we use a significance level of α=10%{“version”:”1.1″,”math”:”α=10%”}. Find the rejection region. SHOW ALL YOUR WORK c. What conclusion do you make based on the data? Explain your answer.

Suppose that a monopolistically competitive firm is facing the following long run average cost (LAC) curve (where Q represents the firm’s output):LAC = 84.5 – 3Q + 0.06Q2 Assume further that the firm is facing the following inverse demand function: P = 60.5 – 0.6QWhat is the profit-maximizing output for the firm in the long-run?
