⇢ Here, the question has given us the data that is 15, 17, 15, 16. 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 15.75 (16).

GIVEN:-

⟶ Data = 15, 17, 15, 16

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 = 4

↬ N = 4

↬ Mean = 15 + 17 + 15 + 16

↬ Mean = 63 / 4

↬ Mean = 63 / 4 = 15.75

↬ Mean = 15.75

↬ We can round of it to its nearest whole.

↬ Mean = 16

Hence, we got the answer. The mean is 15.75 (16).
