The accompanying table shows the population (in hundreds of thousands) and the number of motor vehicle fatalities in 10 states. Complete parts a through e. Click the icon to view the data table. a. Do you expect the correlation to be positive or negative? Why? The correlation and slope will be because states with a larger population will most likely have a number of motor vehicle fatalities. b. Make a scatterplot of the data with population in hundreds of thousands. Be sure that population is the x-variable and motor vehicle fatalities is the y-variable. Choose the correct scatterplot below. O A. в. c. OD. 2000, 2000- 2000- 2000- 1000- 1000- 1000- 1000- 0- 0- 200 100 200 Pop 200 100 Pop 100 200 Pop 100 Pop c. Report the correlation.
