Suppose that the TOEFL Writing score follows a Normal distribution with an average of 15 and a standard deviation of 2. A random sample of eight TOEFL test-takers is drawn. a) Provide a description of the most appropriate statistic. [2] b) Identify the sampling distribution of answer you have in part (a). [4] c) What is the probability that the average TOEFL Writing score of the eight randomly selected TOEFL test-takers.

Suppose that the multiple linear regression model yi=xiT+ei holds for i=1,,n, where the ei are independent errors, with E(eiX=xi)=0 but, unlike the standard setting, with different variances Var( eiX=xi)=i2. a) Show that the OLS estimate ^=(XTX)1XTY is still an unbiased estimate of . That is, show that E[^X]= under the model assumptions. b) Write the variance matrix of the errors ei as a diagonal matrix, say , with diagonal elements (12,,n2). Show that Var(^)=(XTX)1XTX(XTX)1..

Suppose that, during the course of human history, whales have evolved to be better able to avoid human hunters. Given what you know about evolution, which one of these things likely played the biggest role in contributing to this evolutionary process? Whales that happened to have genes that allowed them to stay underwater longer survived. These whales then passed those genes on to their offspring. Some whales were better at having offspring than other whales. This caused them to stay underwater longer (where they were harder for people to find). As whales were being hunted, some of them underwent mutations that allowed them to stay underwater longer (where they were harder for people to find)..

Suppose that, for n observations y1,,yn, we have specified a multiple linear regression model of the form yi=0+1xi1+2xi2+ei where the ei are uncorrelated errors, with E(eiX)=0 and Var(eiX)=2. Consider the situation where we are interested not in the values of the coefficients 1 and 2 separately, but instead in their difference =12. a) Show that the estimator ^=^1^2 is an umbiased estimator of . That is, show that E(^X)= b) Derive an expression for the variance of this estimator, Var(), in terms of the relevant entries of the variance-covariance matrix Var(), where is the OLS estimator of =(0,1,2)T..

Suppose N > 0 firms make a simultaneous and one-time entry decision whether to enter a new market. Entry requires expending a sunk cost E 0, and entering firms produce homogeneous products. If only one firm enters, then it is a monopolist that earns profit M > 0, not counting the entry cost. If more than one firm enters, then severe price competition leads each entering firm to earn 0 profit, not counting the entry cost. Assume that E < M , so that entry can possibly be profitable. Specify a firms probability of entry in a Nash equilibrium of the game in which all firms enter with the same probability.

Suppose Margie is engaged to Dennis on April 16, 2025. Dennis wants to accumulate funds for retirement. He will save $300 per month for the 30 years following their marriage. Assuming monthly compounding. If he earns a constant return of 8%. Now suppose that Dennis is unlucky and earns a -16% return for the first five years of his investment. Then the market rebounds and produces 12.8% for the remaining 25 years of his investment. What was his arithmetic average rate of return on his investment in this case?.
