Answer:

d. 4

Step-by-step explanation:

The degree of freedom is the amount of independent data set used to calculate an estimate. The degree of freedom is quite different from the sample size (n). It is calculated by subtracting one(1) from the total value of the data set (sample size (n)).

From the information given:

The sample size is the number of people in the same group

sample size n = 5

degree of freedom = n - 1

= 5 - 1

= 4
