An electric car is a great way to save a lot of money on gas. The chart below contains data about the sales of electric cars in the U. S. from 2011, the first year electric cars were commercialized, through 2016.
(a) Construct a scatterplot for the data provided to represent the number of electric cars sold each year. Be sure to number and label your axes, and explain any choices you made in scaling your graph.
(b) Estimate a good line of fit for these data. What is the meaning of the slope and vertical axis intercept you have estimated in the context of the problem?
(c) Writers in automotive magazines have created nicknames for the following years:
2014–15: “the year of the slide”
2015–16: “the year of the comeback”
Explain the meaning of these nicknames within the context of the data. Use your graph to explain the general trend in electric car sales from 2011 through 2016.
(d) Use your linear model from part (b) to predict in what calendar year the number of electric cars sold will reach 300,000.
