You have collected data for 104 countries to address the difficult questions of the determinants for differences in the standard of living among the countries of the world. You recall from your macroeconomics lectures that the neoclassical growth model suggests that output per worker (per capita income) levels are determined by, among others, the saving rate and population growth rate. To test the predictions of this growth model, you run the following regression:
You have collected data for 104 countries to addre = 0.339 – 12.894 × n + 1.397 × SK, R2=0.621, SER = 0.177
(0.068) (3.177) (0.229)
where RelPersInc is GDP per worker relative to the United States, n is the average population growth rate, 1980-1990, and SK is the average investment share of GDP from 1960 to 1990 (remember investment equals saving). Numbers in parentheses are for heteroskedasticity-robust standard errors.
Calculate the t-statistics and test whether or not each of the population parameters are significantly different from zero.
The overall F-statistic for the regression is 79.11. What is the critical value at the 5% and 1% level? What is your decision on the null hypothesis?
You remember that human capital in addition to physical capital also plays a role in determining the standard of living of a country. You therefore collect additional data on the average educationalattainment in years for 1985, and add this variable (Educ) to the above regression. This results in the modified regression output:
= 0.046 – 5.869 × n + 0.738 × SK + 0.055 × Educ, R2=0.775, SER = 0.1377
(0.079) (2.238) (0.294) (0.010)
How has the inclusion of Educ affected your previous results?
(d) Upon checking the regression output, you realize that there are only 86 observations, since data for Educ is not available for all 104 countries in your sample. Do you have to modify some of your statements in

Ответ:
75%.
3 out of 4 means 3/4
And if you divide 3/4 the answer is .75
So multiply by 100( because to convert decimal to percent you have to multiply by 100, or move the decimal place two places to the right) and you get 75
Slap a percent sign on there and you have 75%
