A simple hypothesis is that people with larger brains are more intelligent and thus have higher IQ scores. Does the scatterplot support that ...Refer to Data Set 13 in Appendix B and use the 21 pelvis (PLVS) deceleration measurements from the car crash tests.

In 1986, the New York City subway fare cost $1, and as of this writing, it now costs $2, so the price doubled. In the accompanying graph, the $2 bill is twice as long and twice as tall as the $1 bill. Listed below are the amounts (million metric tons) of carbon monoxide emissions in the United States for each year of a recent ten-year period. The data are listed in order. Construct the graph that is most appropriate for ...
