2 correlation is most likely due to coincidence, a common underlying cause, or a direct cause. Explain your answer.9. Guns and Crime Rate. In one state, the number of unregistered handguns steadily increased over the past several years,and the crime rate increased as well.10. Cheese and Deaths. One study showed that there is a correla-tion between per capita cheese consumption and number ofpeople who die by becoming tangled in their bedsheets. Onevariable increased while the other decreased over time.11. Study Time and Test Scores. Statistics students find that asthey spend more time studying, their test scores are higher.12. Divorce and Margarine. Data from the National VitalStatistics Reports and the U.S. Department of Agriculture.show that over the past several years in Maine, the divorcerate declined and per capita margarine consumption alsodeclined.13. Traffic Lights and Car Crashes. It has been found that as thenumber of traffic lights increases, the number of car crashesalso increases.14. Galaxy Distance and Speed. Astronomers have discoveredthat, with the exception of a few nearby galaxies, all galax-ies in the universe are moving away from our solar system.Moreover, the farther away the galaxy is, the faster it is mov-ing away.15. Gas and Driving. It has been found that when gas prices.increase, the distances that vehicles are driven tend to getshorter.16. Swimming and Nuclear Power. Data from the Centers forDisease Control and the Department of Energy show that as thenumbers of people who drown in swimming pools increases,the power generated by nuclear plants also increases.17. Outlier Effects. Consider the scatterplot in Figure 7.15.1.21.00.80.60.4-0.2-002 04 0.6 0.810 12 14Figure 7.150(continue
