A college football coach wants to know if there is a correlation between his players leg strength and the time it takes for them
to sprint 40 yard. He sets up the following test 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. Table shows the average number of leg press repetitions and the average 40 yard dash time (in seconds) for seven randomly selected players. What is the equation of the line of best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Round any values to the nearest 10th if necessary
