a sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer teams leg strength and the time it takes for them to 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 everyday. the 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 for the line of the best fit. how many seconds should he expect a player to take to run 40 yards if the player can do 20 leg press repetitions? round any values to the nearest tenth if necessary.
