An environmental activist wants to look at the relationship between number of incentive actions taken by the government and the percent share that electric cars make up of overall new vehicle sale in several
metropolitan areas. The data show a linear pattern with the summary statistics shown below:
mean
standard deviation
SE
5.2
2=number of incentive actions
ī=12.2
y=electric vehicle share of new vehicle sales (percent) y = 1.1
8y = 1.3
r=0.65
Find the equation of the least-squares regression line for predicting the electrical vehicle share of new
vehicle sales from the number of incentive actions the government takes.
