_ Use the results from the regression you just ran with per capita GDP and health care. You already found R square for this regression. What is the estimated variance of the error term (this is the mean-squared error)? Answer to the nearest integer. Hint this number should be less than 1,000,000. D Question 7 1 pts Use the results from the regression you just ran with per capita GDP and health care. You already found R square for this regression. What is the estimated standard deviation of the error term? Answer to the nearest integer. D Question 12 1 pts Using the results from the regression you ran, what is the predicted per capita spending on health care for a country with per capita GDP of $20,000? Answer to the nearest integer, do not include a dollar sign, you may round up or down as usual. Hint your answer should be between 100 and 10,000 which is not much of a hint but it tells you if you are way out of the ballpark. D Question 14 1 pts If the estimated slope of the simple linear regression is negative then this means that for all pairs of observations is Xi > xj then Vi
