A college football coach wants to know if the is a correlation between his players' 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 every day. The tables 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

How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Leg Press (reps)|40-yard Dash (s) 15 |5.2 18 |6.3 8 |6.8 30 |8.2 26 |8.0 12 |5.3 21 |5.9
@ivettef365 the second post is the full one
I would make a graph and plot each point
you don't have multiple choice answers?
no its a response
@ivettef365
just trying to understand
graph and plot your points and it wall make a lot of sense
this question is hard to explain, but if you try graphing it you will see it is a positive correlation, I believe that the last question is approx 6 that means according to the graph if the player can do 22 leg-press is expected to run the 40 yards in 6 seconds
there is an outlines which is the 8! 6.8
the equation of the line believe is something like y = 0.5 x + 4 not too sure, this questions does not have an exact answer is just what best fit
thank u
you're welcome :)
