help me with this ap statistics

2) Two measures of a baseball player's effectiveness as a hitter are the number of hits he makes in a season and the number of times he "bats in" a run (known as "Runs Batted In" or RBIs). Can we predict a batter's RBIs from hits? Below is numerical and graphical output from a computer regression of RBIs on Hits for 8 randomly selected Major League Baseball batters in 2012.

How accurate do you think this prediction would be and why? b) Check the conditions for a confidence interval for B, the slope of the population LSRL. c) Calculate and interpret a 95% confidence interval for B
