Question

A Baseball coach was trying to predict the number of RBIs players hit based on the amount of time they spend in the batting cage.

Assuming the slope (or change in DV for every change in the IV) is 5 and the Y intercept is 10, what will the predicted RBI total be for player 1 who spent 12 hours in the batting cages compared to the predicted RBI total for player 2 who spent 4 hours in the batting cages?

What would you predict for a player who spent 9 hours in the batting cages?

Show the formula used

Answer 1

Formula is:

Player 1		Hence, For player 1, 70  RBIs players hit is the prediction
Player 2		Hence, For player 2, 30  RBIs players hit is the prediction.
Player who spent 9-hour x = 9		Hence, For the player who spent 9 hours, 55 RBIs players hit is the prediction.

Explanation:

We, Know the formula for Linear Equation:

So, According to the question:

Slope = b1 = 5

Intercept = b0 = 10

Therefore, Equation is:

Now, Player 1 spent 12 hour which means x = 12

ans.

Hence, For player 1, 70  RBIs players hit is the prediction

Now Player 2 spent 4-hour means x = 4

Hence, For player 2, 30  RBIs players hit is the prediction.

Predict For Player who spent 9-hour x = 9 is:

ans.

Hence, For the player who spent 9 hours, 55 RBIs players hit is the prediction.
