Question

What is the relationship between the attendance at a major league ball game and the total number of runs scored? Attendance figures (in thousands) and the runs scored for 9 randomly selected games are shown below.

 

Attendance 24 54 59 17 32 58 30 26 18
Runs 5 14 14 5 7 8 10 6 4
  1. Use the model to predict the runs scored at a game that has an attendance of 34,000 people.
    Runs scored =  (Please round your answer to the nearest whole number.)  

  2. Interpret the slope of the regression line in the context of the question:  
    • The slope has no practical meaning since the total number runs scored in a game must be positive.
    • As x goes up, y goes up.
    • For every additional thousand people who attend a game, there tends to be an average increase of 0.18 runs scored.


  3. Interpret the y-intercept in the context of the question:
    • If the attendance of a baseball game is 0, then 2 runs will be scored.
    • The average runs scored is predicted to be 2.
    • The y-intercept has no practical meaning for this study.
    • The best prediction for a game with 0 attendance is that there will be 2 runs scored.
