Economists believe that higher levels of adult educational attainment contribute to higher levels of GDP per capita. To analyze this belief you decide to estimate a regression of GDP per capita (y) on the educational attainment (x). You collect the data for a random sample of 15 countries. The data for each country include GDP per capita measured in $ and the educational attainment measured as the average year of total schooling for a person of 15 years and older. Using the data, you estimate the regression equation and, testing the significance of the slope, you find that the p-value equals 0.0127 (think about the p-value for the slope from the Excel output).
Required:
At a 5% significance level, what can you conclude based on the p-value?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
