In-Class Activity #7

If a baseball team scores 763 runs and allows 614 runs, how many games do we expect the team to win?

Using the linear regression model constructed during the lecture, enter the number of games we expect the team to win:

RS = Runs Scored RA = Runs Allowed

RS <- 763
RA <- 614

Get runs difference by subtracting RS and RA.

RD = Runs Difference

RD <- 149

Get number of Wins (W) W = 80.8814 (Intercept) x 0.1058 (Coefficient for RD) * RD

80.8814 + (0.1058 * RD)

[1] 96.6456

We can expect the team to win ~97 times.
