A college football coach wants to know if there is a correlation between his playersβ leg strength and the speed at which they can sprint 40 yards. He sets up the following test and records the data:
Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The table shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for 7 randomly selected players. What is the equation of the line of best fit? How fast could he expect a player to run 40 yards if that player can reach 22 leg-press repetitions? Round any value to the nearest tenth, if possible.
Leg Press 15 18 8 30 26 12 21
40-yard Dash 5.2 6.3 6.8 8.2 8.0 5.3 5.9
