Question

The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot. An analysis was completed and the computer output is shown.
Using the computer output, what is the predicted foot length for a student with an arm span of 160 cm?

5.79 cm
22.15 cm
29.76 cm
29.80 cm

Answer 1

Based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.

What are Scatterplots?

• Scatter plot is a graphical tool that shows a trend between a dependent and independent variable.
• The trend line can be used to make predictions.

Given the scatter plot as shown above, at 160 cm arm length spam, if we trace it up to the trend line, the corresponding predicted foot length lies between 21 - 23 cm.

Therefore, based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.
