(a) Find the​ least-squares regression line for males treatingthe number of licensed drivers as the explanatory​ variable, x, andthe number of fatal​ crashes, y, as the response variable. Repeatthis procedure for females.

(b) Interpret the slope of the​ least-squares regression linefor each​ gender, if appropriate. How might an insurance companyuse this​ information?

(c) Was the number of fatal accidents for 16 to 20 year oldmales above or below​average? Was the number of fatal accidents for21 to 24 year old males above or below​average? Was the number offatal accidents for males greater than 74 years old above or below​average? How might an insurance company use this​ information? Doesthe same relationship hold for​ females?
