Question 28.14. From a sample of 209 firms, Wooldridge obtained the following regres-sion results":log (salary) = 4.32 + 0.280 log (sales) + 0.0174 roe + 0.00024 rosse = (0.32) (0.035)(0.0041)(0.00054)R = 0.283where salary = salary of CEOsales = annual firm salesroe = return on equity in percentros = return on firm's stockand where figures in the parentheses are the estimated standard errors.a. Interpret the preceding regression taking into account any prior expec-tations that you may have about the signs of the various coefficients.b. Which of the coefficients are individually statistically significant at the5 percent level?c. What is the overall significance of the regression? Which test do youuse? And why?d. Can you interpret the coefficients of roe and ros as elasticity coeffi-cients? Why or why not?

1. Davidson ("Update on Ozone trends in California's South Coast Air Basin" Air and Waste). Studied the ozone levels in the South Coast Air Basin of California for the years 1976-1991. He believes that the number of days the ozone levels exceeded 0.20 ppm (the response) depends on the seasonal meteorological index, which is the seasonal average 850-millibar temperature (the regressor) Use the information provided below to answer the following questions I = 17.34 y = 72.31 Syy = 9419.44 S = 6.3796 Sy = 97.5814 SSR = 1492.6 n = 16 а.

Q2. You collected 500 weeks of data (2500 days total). Based on that you find Tuesday's mean return is 12 bps. Mean return of all days is 2 bps. Stdev across all days is 100 bps. There is no noticeable difference b/w Tuesday stdev vs other weekdays' stdev. Based on q1c find D Q1c. what is the mean log return and stdev of log return over one year period and four year period (assuming 252 trading days per year)? Q1d. based on Q1c what is the probably of losing money (negative log return) or doubling your money (total log return = ln(2)) over 1 year and 4 year period?

The results of an analysis, on the makeup of garbage, done by the Environmental Protection Agency, was published in 1990. Some of the results are given in the following table, which for various years gives the number of pounds of waste that an average person generates on a daily basis. From 1970 to 1988, what is the average rate of change of daily plastic waste generated?

Suppose ₁ and ₂ are true mean stopping distances at 50 mph for cars of a certain type equipped with two different types of braking systems. The data follows: m = 9, x = 113.3, s₁=5.01, n = 9, y = 129.6, and s₂ = 5.34. Calculate a 95% CI for the difference between true average stopping distances for cars equipped with system 1 and cars equipped with system 2. (Round your answers to two decimal places.)
