Suppose you are interested in looking at the determinants of a professional's salary, and use the following econometric model to do so: salary = β0 + 81 GPA + 82 ezper + β3 gender + β4 major + u
where
salary = salary in dollars
GPA = grade point average throughout college
exper = years of work experience gender
major = college major
u = error term
You take a sample of 110 individuals and collect data on each person's salary, college GPA, years of experience, gender, and college major. An unbiased, observable estimator of the variance of the error term (σ2) is σ2 =.

Suppose that xtel currently is selling at $40 per share. you buy 500 shares using $15,000 of your own money, borrowing the remainder of the purchase price from your broker. the rate on the margin loan is 8%. a. what is the percentage increase in the net worth of your brokerage account if the price of xtel immediately changes to (a) $44; (b) $40; (c) $36? (leave no cells blank - be certain to enter "0" wherever required. negative values should be indicated by a minus sign. round your answers to 2 decimal places.) b. if the maintenance margin is 25%, how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.) c. how would your answer to requirement 2 would change if you had financed the initial purchase with only $10,000 of your own money? (round your answer to 2 decimal places.) d. what is the rate of return on your margined position (assuming again that you invest $15,000 of your own money) if xtel is selling after one year at (a) $44; (b) $40; (c) $36? (negative values should be indicated by a minus sign. round your answers to 2 decimal places.) e. continue to assume that a year has passed. how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.)
