question 24 PLEASE SEND ME A PICTURE OF YOUR RESPONSE
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) 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 +0 (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 = * + 0 (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 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 your choice (Use the answer from part a to find this answer ) A. If the average age of all female licensed drivers increases by 1, then the number of fatal crashes increases by , on average. B. If the number of female licensed drivers increases by 1 (thousand), then the number of fatal crashes increases by on average. O C. If the number of fatal crashes increases by 1, then the number of female licensed drivers increases by thousand, on average D. It does not make sense to interpret the slope. The slope of the Data for licensed drivers by age and gender. to be involved in (c) Was the numb ber of fatal accidents for 21 to 24 year old males above d above or below average?
