The table lists weights (pounds) and highway mileage amounts (mpg) for seven automobiles. Use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation?| Weight (lb) | 2820 | 3185 | 3825 | 4150 | 4330 | 2440 | 3575 ||-------------|------|------|------|------|------|------|------|| Highway (mpg) | 33 | 32 | 27 | 24 | 23 | 38 | 28 |Which scatterplot below shows the data?- **Option A**- **Option B**- **Option C**- **Option D**(Images of scatterplots A, B, C, and D are displayed, plotting Highway (mpg) against Weight (lb) on the axes.)Is there a linear relationship between weight and highway mileage?- **A.** No, there appears to be a relationship, but it is not linear.- **B.** Yes, as the weight increases the highway mileage increases.- **C.** Yes, as the weight increases the highway mileage decreases.**Explanation of Scatterplots:**- **Scatterplot A:** Shows a random distribution of points without a clear pattern.- **Scatterplot B:** Shows a slight upward trend.- **Scatterplot C:** Shows a clear downward trend, indicating that as weight increases, mileage decreases.- **Scatterplot D:** Shows random points with no discernible trend.The correct choice for the scatterplot that shows the data is **Option C**, and the correct conclusion about the linear relationship is **C**, as the weight increases the highway mileage decreases. **Question:** Is there a linear relationship between weight and highway mileage?**Options:**- **A.** No, there appears to be a relationship, but it is not linear.- **B.** Yes, as the weight increases the highway mileage increases.- **C.** Yes, as the weight increases the highway mileage decreases.- **D.** No, there appears to be no relationship.*Note: There are no graphs or diagrams accompanying this text.*

(ii) Suppose Country B is similar to Country A in the amount of government expenditures and the level of real GDP at full employment. But instead of a proportional tax system, Country B has a lump-sum (regressive) tax system that balances the budget at all levels of GDP. Graph the tax revenues for this country. Instructions: Use the tool provided 'Tax revenues' to illustrate the country's tax revenues. Plot the first point of the line where real GDP is $20 billion and the second point where real GDP is $80 billion. Plot only the endpoints of the line. $25 Tools $20 Tax revenues $15 $10 G $5 $20 $40 $60 $80 $100 Real domestic output, GDP (billions) Government expenditures, G, and tax revenues, T (billions)
