Y-AxisX-AxisThe above graph presents the relationship between pollution per capita andeconomic growth. Undeveloped countries pollute very little. As the countrygrows, pollution increases (think India and China). Finally, as a country furthergrows and prioritizes lower pollution, pollution decreases.Given the following scatter plot, does it make sense to compute thecorrelation?Yes, because there is a strong relationship between the two variablesNo, because the relationship is nonlinearNo, because the units of the two variables are different.No, because economic both variables are categorical

The given scatter plot shows the relationship between pollution per capita and economic growth.

Risky Drivers The following table gives the policereported crashes per million miles traveled for differentage groups.a. Create a scatter plot of the data, with x equal tothe age of the drivers and y equal to the number ofcrashes per million miles travel.b. Find the quartic function that is the best fit for thedata, where x is the age of the drivers and y equalsthe number of crashes per million miles traveled.Report the model with four significant digits.c. Graph the function and the data on the same set ofaxes, for x = 15 to x = 85.d. At what ages is the number of crashes less than 3,according to the model?
For non-linear relationships, correlations can give correct results. Group of answer choices, jmultiple choice: never, as this is not meaningful this is not answerable sometimes, since non-linearity can reduce to linearity always, as correlations are independent of linearity
