Answer:
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 x = x=x, equals number of incentive actions x ˉ = 12.2 x ˉ =12.2x, with, \bar, on top, equals, 12, point, 2 s x = 5.2 s x =5.2s, start subscript, x, end subscript, equals, 5, point, 2 y = y=y, equals electric vehicle share of new vehicle sales (percent) y ˉ = 1.1 y ˉ =1.1y, with, \bar, on top, equals, 1, point, 1 s y = 1.3 s y =1.3s, start subscript, y, end subscript, equals, 1, point, 3 r = 0.65 r=0.65r, equals, 0, point, 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. Round your entries to the nearest hundredth.
