Answer:
17
Step-by-step explanation:
Degrees of freedom here are 18-1, or 17.
If the size of the random sample is 18. Then the degree of freedom of the random sample is 17.
Random sampling is the method of selecting the subset from the set to make a statical inference.
If the sample size is 18, then the degrees of freedom will be given as
Degree of freedom = n - 1
Where n is the size of the random sample
Then we have
Degree of freedom = 18 - 1
Degree of freedom = 17
