mean=Sum of all observation/total no of observation
since mean is given=12
12= 16+12+8+11+10+p+9/7
12=56+p/7
12×7=56+p
84=56+p
p=84-56
p=28

given:- mean=12, total no. of observations=7
sol:- since mean = sum of all observations / total no. of observations
therefore,
12 = 16+12+8+11+10+p / 7
84 = 57 + p
84 - 57 = p
27 = p
=> p = 27
