9. (14 pts) Based on data of car deaths in US Car deaths in US 50,000 45,000 .. . . ......... 40,000 ......'s.................... . . 35,000 . 30,000 25,000 20,000 y =-400.71x + 845240 15,000 R2 = 0.4604 10,000 5,000 1995 2000 2005 2010 2015 2020 The regression line is y = -400.71x + 8452.40, where x = year and y = deaths in USA. The value of r is 0.4604 (a) Use the regression line to estimate the car deaths in 2012, to the nearest tenth of a degree. Show some work. (b) Use the regression line to predict the deaths in 2025, to the nearest tenth of a degree. Show some work.(c) What is the slope of the regression line and what are the units of measurement? application. In a sentence, interpret what the slope is telling us, in the context of this real-world (d) What is the value of the correlation coefficient, r? Also, interpret its value: Looking at the graph and the size of r, do you judge the strength of the linear relationship to be very strong, moderately strong, somewhat weak, or very weak
