Question
paterms Using these observations, you estimane the folonaing regression q. s consumetion and Y is disposable income. The estimate of Di will tell yos thas yoswe have coected a e of observations from over 100 households and theie oee A)A where C is consumption and Y B) The amount you need to consome to survive 22 Imagine that you were told that the -statistic for the slope coefficiert regression line A) points ef the test score 6.9-2.28 x STR was 4.38. What are the units of measarement B) namber of students per teacher C) D) standard deviations TestScore STR 23- The critical value of a two-sided Nest computed from a large sample A) is 1.64 if the significance level of the test is 5%. B) cannot be calculated unless you know the degrees of freedom. C) ?S 1.96 if the significance level of the test is 5%. D) is the same as the p-value. 24. The 95% confidence interval for ?1 is the interval C @1-196SED.+1.96sE) D)(f1-196, ?1 + 1.96). The error term is homoskedastic if A) varud x-x) is constant for i . i, B) vartud Xi-x) depends on x C) X is normally distributed D) there are no outliers. 25· , n. 26. Consider the estimated equation TestSor 698.9-2.28x STR. R2-0.051, SER -18.6 (10.4) (0.52) The -statistic for the slope is approximately A) 4.38 B) 67.20 C) 0.52 D) 1.76Explanation / Answer
20) B is correct
A regression is always run on a sample and because of which linear regression is also called sample regression function.
21) D is correct
Slope coefficient beta one gives the you the unit change in consumption due to per unit change in income.
22) A is correct
t statistic has unit of test scores point. It is the ratio true value of parameter and it's standard error.
23) C is correct
At 5% level of significance, critical z score is 1.96.
These critical values are calculated from z statistics table.
