Answer:

Step-by-step explanation:

Hello!

In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.

In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.

If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n

For the students that received the phone call:

n= 19 + 9= 28

The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68

The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32

For the students that didn't receive the phone call:

n= 8 + 6= 14

The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57

The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43

I hope this helps!
