Answer:
Option 3)
Explanation:
Given that a football player notices a pattern in the points he scored per game last season.
Here number of points he scored is the dependent variable say y.
Other variables given are
1) The average high temperature on game day
2)The color of the opposing team's jerseys
3)The number of times he caught a pass successfully
4)The number of hot dogs sold during each game
On analysing these four variables we find that temperature is least associated with points of football player.
Similarly colour of jerseys of opposing team has nothing to do with the points scored
The number of hot dogs sold may depend on the number of spectators and not on the points.
But Option 3) The number of times he caught a pass successfully
is really strongly correlated with football player points.
