Listen17. In a study, nine tires of a particular brand were driven on a track under identicalconditions. Each tire was driven a particular controlled distance (measured inthousands of miles), and afterward the tread depthlvas measured. Tread depth ismeasured in "mils." Here, 1 mil is 0.001 inch. The least-squares regression line wascomputed, and added to a scatterplot of these data. On the plot, one data point ismarked with an "X". This data point will be referenced in Question 15.ENG* 4)Tread Depth (Mils) Attempt 1The equation of the least-squares regression line is:Tread Depth = 360.64 - 11.39x (thousands of miley)Also, 2= 0.953.Which of the following statements is true?a) About 95.3% of the variation in tread depth is explained by the regression on miles.O b) According to the least-squares regression line, the groove depth of a new tire (driven0 miles) is predicted to be 360.64 mils.c) According to the least-squares regression line, we would predict a decrease in groovedepth of 11.39 mils for each 1000 miles driven on a tire.d) All of the above.
