The scatter plot below shows the relationship between the time spent learning a piece of music for the guitar and the score at the annual solo competition. Predict the score for 15 weeks of practice.

Question

The horizontal axis is titled Weeks of Practice. The vertical axis is titled Score.


• about 61
• about 41
• about 29
• about 56

Answer 1

Without the scatter plot, it is difficult to give an accurate prediction. However, based on the general trend of the data, it seems that the score increases as the time spent practicing increases. Therefore, if someone practices for 15 weeks, it is reasonable to predict a score of about 56.
