The data in the table represent the number of licensed drivers in various age groups and the number of fatal accidents within the age group by gender. Complete parts (a) to (c) below. (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. Data for licensed drivers by age and gender. y=x+O (Round the slope to three decimal places and round the constant to the nearest integer as needed.) Find the least-squares regression line for females. yーロx+ロ (Round the slope to three decimal places and round the constant to the nearest integer as needed.) Number of Number ot Number of Male Fatal Licensed Drivers Crashes Number of Female Fatal Licensed Drivers Crashes Age (000s) < 16 (b) Interpret the slope of the least-squares regression line for each gender, if appropriate. How might an insurance company use this information? (Males) (000s) (Females) 12 227 12 77 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 16-20 6,424 5,180 6,139 2,113 21-24 6,961 5,016 6,816 1,532 O A. If the average age of all male licensed drivers increases by 1, then the number of fatal crashes increases by, on average.

If the number of male licensed drivers increases by 1 (thousand), then the number of fatal crashes increases by, on average.

If the number of fatal crashes increases by 1, then the number of male licensed drivers increases by thousand, on average. >74 4,803 2,022 5,375 962 (Round to three decimal places as needed.) O 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 you Print Done A. If the average age of all female licensed drivers increases by 1, then the number of fatal crashes increases by , on average. (Round to three decimal places as needed.) O B. If the number of female licensed drivers increases by 1 (thousand), then the number of fatal crashes increases by O, on average. (Round to three decimal places as needed.) O C. If the number of fatal crashes increases by 1, then the number of female licensed drivers increases by (Round to three decimal places as needed.) | thousand, on average. D. It does not make sense to interpret the slope. The slope of the regression line for males is V that for females. This means that males tend to be involved in females. An insurance company may use this information to argue for
