The linear correlation coefficient between the weight of a car and its miles per gallon in the city is r= - 0.972. The least-squares regression ine treating weight as the explanatory variable and miles per gallon as the response variable is y = - 0.0070x + 44.4405. Complete parts (a) and (b) below. Click the icon to view the data table. (a) What proportion of the variability in miles per gallon is explained by the relation between weight of the car and miles per gallon? The proportion of the variability in miles per gallon explained by the relation between weight of the car and miles per gallon is%. (Round to one decimal place as needed.)

Complete parts (a) through (c) below. Click the icon to view the data table. a) Find the least-squares regression line for males treating the number of licensed drivers as the explanatory variable, x, and the number of fatal crashes, y, as the response variable. Repeat this procedure for females. Find the least-squares regression line for males. y =]x+ (Round the x coefficient to three decimal places as needed. Round the constant to the nearest integer as needed.) Find the least-squares regression line for females. y = x+ (Round the x coefficient to three decimal places as needed. Round the constant to the nearest integer as needed.) (b) Interpret the slope of the least-squares regression line for each gender, if appropriate. How might an insurance company use this information? What is the correct interpretation of the slope of the least-squares regression line for males? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Use the answer from part a to find this answer.) A. If the number of fatal crashes increases by 1, then the number of male licensed drivers increases by | thousand, on average. O B. If the number of male licensed drivers increases by 1 (thousand), then the number of fatal crashes increases by , on average. C. If the average age of all male licensed drivers increases by 1, then the number of fatal crashes increases by , on average. D. It does not make sense to interpret the slope. What is the correct interpretation of the slope of the least-squares regression line for females? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
