Question

based on the scatter plot below, which is a better prediction for y when x = 30? 60 0

Explanation:

Step1: Observe the scatter - plot trend

By looking at the scatter - plot, we can see that as $x$ increases from 0 to 100, $y$ generally decreases. When $x = 30$, we need to estimate the value of $y$ based on the distribution of points.

Step2: Locate the $x = 30$ position

We find the vertical line corresponding to $x = 30$ on the $x$-axis and then see where the points are concentrated around this $x$-value. The points around $x = 30$ seem to be in the range of $y$ values close to 60.

Answer:

60
