ieh of the following statements is true? a) About 95.3% of the variation in tread depth is explained by the regression on miles. b) According to the least-squares regression line, the groove depth of a new tire (driven 0 miles) is predicted to be 360.64 mils. Oc) According to the least-squares regression line, we would predict a decrease in groove depth of 11.39 mils for each 1000 miles driven on a tire. d) All of the above.
