all Verizon 1:44 PM 62%-, Yi 2 points mintrostat9 10.e.031 defective How are returns on common stocks in overseas markets related to returns in one countries markets? Consider measuring the countries returns by the annual rate of return on the index A and overseas returns by the annual rate of retun on index B. Both are recorded in percents. We will regress the B returns on the A returns for the years 1991 to 2014. Here is part of the output for this regression. The regression equation is B--3.21+0.823A. Complete the analysis of variance table by filing in the missing boxes.

Wages also increase because of inflation. By examining a sample of employees at a given point in time, we can look at part of the pictuire. How does length of service (LOS) relate to wages? The data here (data275.dat) is the LOS in months and wages for 60 women who work in Indiana banks. Wages are yearly total income divided by the number of weeks worked. We have multiplied wages by a constant for reasons of confidentiality. (a) Plot wages versus LOS. Consider the relationship and whether or not linear regression might be appropriate.

Explanation / Answer

Question 8 Solution

MS(Regression) = 5551.3

SSE= TSS-SSR = 10077.5-5551.3 = 4526.2

n=22

DF of SSE = n-2 = 20

MS(Error) = 4526.2/20 = 231.3

DF of TSS = n-1 = 21

F = MS(Regression)/MS(Error) = 5551.3/231.26 = 23.97
