The scatter plot shows the time spent studying compared to test scores for Mr. Stone’s eighth-grade class. Predict the score that a student would earn if she studied for 7 hours. Round your answer to the nearest whole number. Enter your answer in the box.

Question

A scatterplot with about 30 points plotted in an upward trend along with a line of best fit that begins at the point zero comma 49 and passes through the points 5 comma 70, 6 comma 75, and 7 comma 80.

Answer 1

To predict the score for a student who studied for 7 hours using the information from the scatter plot, we can analyze the pattern of the line of best fit.

From your description, we see that the line of best fit starts at the point (0, 49) and increases with study hours. Since the line has passed through the points (5, 70), (6, 75), and (7, 80), we can conclude that:

• At 5 hours, the score is 70.
• At 6 hours, the score is 75.
• At 7 hours, the score is 80.

Since you provided that a student studied for 7 hours, and the plot indicates a score of 80 at that point, we can predict that the score would be 80.

Thus, the predicted score for a student studying for 7 hours is 80.
