Shоw аll the necessаry steps in yоur respоnse. The аnswer alone is not sufficient. Due to improved technology and public-service campaigns, the number of collisions at highway-railroad crossings per year as declined since 1985. Let n be the number of collisions (in thousands) for the year that is t years since 1980. Year Number ofCollisions(thousands) 1985 7.1 1990 5.7 1995 4.6 2000 3.5 2005 3.1 2007 2.7 a. Use the linear model n = -0.211t + 8.06 to estimate the number of collisions in1998.b. Find the n-intercept of your linear model. What does it mean in this situation?
