Math Problem Statement
Use a trend line to make a prediction for y when x = 6, based on the provided scatter plot.
Solution
From the image, the question asks to use a trend line to predict the value of when , based on the scatter plot data.
Steps:
-
Draw a Trend Line:
- Observing the scatter plot, visually approximate a line that best fits the points. It should pass through the center of the data distribution, balancing the number of points above and below.
-
Estimate for :
- Locate on the graph and determine where it intersects the trend line.
- From that point, estimate the corresponding -value.
