Question

based on the scatter plot below, which is a better prediction for y when x = 21?
(scatter plot with x-axis from 0 to 100, y-axis from 0 to 100, green dots plotted. options: 56, 3)

Explanation:

Step1: Analyze the scatter plot trend

The scatter plot shows a positive correlation (as \( x \) increases, \( y \) generally increases). For \( x = 21 \), we look at the region where \( x \approx 20 \). The points around \( x = 20 \) have \( y \)-values around 40 - 70, not near 3.

Step2: Evaluate the options

56 is within the typical \( y \)-range for \( x \approx 21 \), while 3 is far from the trend.

Answer:

56
