First we need to know the observations.
15+(-3)=12(FIRST OBSERVATION)
15+0=15(SECOND OBSERVATION)
15+(-2)=13(THIRD OBSERVATION)
15+4=19(FOURTH OBSERVATION)
15+6=21(FIFTH OBSERVATION)
15+1=16(SIXTH OBSERVATION)
15+1=16(SEVENTH OBSERVATION)
Mean is the average no.
MEAN = SUM OF OBSERVATIONS ÷NO. OF OBSERVATIONS
= (12+15+13+19+21+16+16) ÷ 7
= 112 ÷ 7
= 16.
16 IS YOUR ANSWER.
