⇢ Here, the question has given us the data that is 18, 22, 15, 20, 25. Now the question has asked us to find the mean. So, we simply have to apply the formula of mean and solve to get the mean.

ANSWER:-

☯ The mean is 20.

GIVEN:-

⟶ Data = 18, 22, 15,20,25

TO FIND:-

⇾ Mean = ?

FORMULA:-

$\to \bf{Mean = \dfrac{Sum \: of \: all\: observations}{Number \: of \: observations}}$

SOLVING BY APPLYING THE FORMULA:-

↬ Mean = Sum of all observations / Number of observations

↬ No. of terms = 5

↬ N = 5

↬ Mean = 18 + 22 + 15 + 20 + 25

↬ Mean = 100 / 5

↬ Mean = 100 / 5 = 20

↬ Mean = 20

Hence, we got the answer. The mean is 20.
