Question

here is a scatter plot that compares hits to at bats for players on a baseball team.
a. how many hits did the player with 475 at bats have?
b. based on the line of best fit, how many hits would you have predicted the player with 475 at bats have?

Explanation:

Part A

Step1: Locate 475 At Bats

Find the x - value (At Bats) of 475 on the scatter plot's x - axis.

Step2: Find corresponding Hits

Look at the blue dot (data point) with x = 475 and find its y - value (Hits). From the plot, the player with 475 At Bats has 130 hits.

Part B

Step1: Locate 475 At Bats on line

Find the x - value of 475 on the x - axis and then find the point on the line of best fit (green line) with x = 475.

Step2: Determine Hits from line

The y - value (Hits) of the point on the line of best fit with x = 475. From the line's slope and intercept, when x = 475, the predicted hits (from the line of best fit) can be calculated or read. Looking at the line, when x = 475, the y - value (Hits) is 150 (since the line seems to follow a pattern where it's increasing, and at x = 500, it's around 150, and 475 is close to 500, and the line's equation or visual inspection shows that at x = 475, the predicted hits are 150).

Part A Answer: 130

Part B Answer: 150

Part A Answer: 130

Part B Answer: 150
