Q : A researcher specities the tollowing model ot human capital HC a t+a,RM +a2Y +a,HS +a SC +asEDH +U Where HC is human capital (for human capital education expenditure is used as a proxy), RM = 1 if a household receives remittances and RM = 0 if a household does not receives remittances, Y = Household income, HS = Household size, SC = total number of school going children per household, EDH = 1 if head of household is literate and EDH = 0 if head of household is illiterate. Using data of 400 households he gets following results (A) HC = -6000+2010RM + 0.11Y - 80HS+805sC + 540EDH (0.02) (15) (105) (140) R(sqaure)= 0.45 SE= (2014) (215) Interpret above results Suppose researcher splits the households into low income households and high income households. He runs separate regressions and finds residuals sum of squares (RSS) 230 and 350 for 180 low income households and . 180 high income households, respectively. Is there any problem of Hetroscedasticity in above model? How do…
Refer back to Example 5.31. Two cars with six-cylinderengines and three with four-cylinder engines are to be drivenover a 300-mile course. Let X1, . . . X5 denote the resultingfuel efficiencies (mpg). Consider the linear combinationY = (X1 + X2)/2 - (X3 + X4 + X5)/3which is a measure of the difference between fourcylinderand six-cylinder vehicles. Compute P(0 <= Y)and P(Y > 2). [Hint: Y 5 a1X1 1 . . . 1 a5X5, witha1 = 1/2 ,…, a5 = -1/3.]
QUESTION A sales representative for Pinnacle Golf, a manufacturer of golf balls, is attempting to convince the pro shop manager of the Whistling Straits Golf Club to carry their recently introduced new line of golf balls that have a larger distance than any of the existing balls that the shop is currently selling. While the “extra” distance is a feature that should make the balls more attractive, the new balls are more expensive than the current balls. If the company’s claim about the new balls is found to be accurate, then the manager will carry the new line of balls. To test the new balls, the pro shop manager asked the club’s golf pro to hit 100 of the top-selling brand of balls and 100 of the new balls. The distance traveled by both the new and current balls was recorded. For this scenario, which of the following would be the proper set of hypotheses? Use the scenario from above question : The manager ran the following output, none of which might be correct. What should…
