Suppose the following table was generated from the sample data of 2020 NASCAR drivers regarding their yearly earnings, number of years on the circuit, and whether or not their car is a Chevrolet. Using statistical software, indicator (dummy) variable for the variable "Chevrolet" and find the regression equation. Is there enough evidence to support the claim that on average drivers of Chevrolets earn more than drivers of other types of cars at the 0.050.05 level of significance? If yes, write the coefficient of the dummy variable in the space provided, rounded to two decimal places. Else, select "There is not enough evidence."
