Let's examine the relationship between GNP per capita and the percentage of respondents willing to pay more in taxes.
a. In this chapter, we used Table 13.4 to illustrate how to calculate the slope and intercept in the regression table. Using Table 13.4 as a model, create a similar table using the data below for GNP per capita and the percentage willing to pay higher taxes.
b. From the table that you created in 10a, calculate a and b and write out the regression equation (i.e., prediction equation).
c. Calculate and interpret error type, E2.
d. Using your answer from 10c, calculate the PRE measure, r2. Interpret.
e. About what percentage of citizens are willing to pay higher taxes for a country with a GNP per capita of 3.0 (i.e., $3,000)? For a GNP per capita of 30.0 (i.e., $30,000)?
