Question

based on the scatter plot below, which is a better prediction for x when y = 68?

Explanation:

Step1: Locate y - value on scatter - plot

Locate $y = 68$ on the y - axis.

Step2: Estimate x - value

Draw a horizontal line from $y = 68$ until it intersects the general trend of the data points. Then draw a vertical line down to the x - axis to estimate the x - value. By visually estimating from the scatter - plot, the x - value seems closer to 37 than 3.

Answer:

37
