A cоmpаny thаt sets up 5k оbstаcle cоurse races did a study where they let x= the number of obstacles they put in the race and y = the average completion time in minutes for that race. They used between 4 and 12 obstacles in their races. They performed linear regression and found the regression equation given below. Use the equation to find/answer: Blank 1: Write a sentence interpreting the value of the slope in context. Blank 2: One race in the data set had 8 obstacles and an average completion time of 55 minutes. Find the residual for this race. Just give the value online. On your work sheet label this as problem 6 and show your work, including the work to get the predicted time.
