i just need help with d-f please, thank you!

Next summer you decide to enjoy the post-Covid world by attending some baseball games. You keep the stats of your
favorite players and decide to examine if there is any connection between Home Runs and Runs Batted In.
a) Fill in the empty cells in the table below. (If you are concerned a portion of the table is not showing up in your
word processer look at the pdf version of the exam).
Home Runs
Runs Batted In

b) Calculate the correlation coefficient (r).
Use Sx=1.414 and Sy = 6.325 while I know you can calculate standard deviations I have gone ahead
and done so for you.
SHOW YOUR WORK. (Write down the equation and plug in the correct values, the correct
answer alone will not get full points.)
r =
C.) Let's say you want to predict how many Runs Batted In a player would have based on their Home Runs. Write
down the general regression equation we could use to do so.
