Question

1. the scatter plot shows the number of absences and average grades for several different students.

a. based on the scatter plot, what average grades would you expect a student to have that has 5 absences?
b. based on the scatter plot, how many absences would you expect a student to have with an 85 average grade?

Explanation:

Step1: Analyze scatter - plot for part a

Look at the points where the number of absences \(x = 5\). Find the corresponding \(y\) - values (average grades).

Step2: Analyze scatter - plot for part b

Look at the points where the average grade \(y=85\). Find the corresponding \(x\) - values (number of absences).

Answer:

a. Looking at the scatter - plot, when the number of absences \(x = 5\), the average grade is approximately \(90\).
b. Looking at the scatter - plot, when the average grade \(y = 85\), the number of absences is approximately \(3\).
