Question

when 15 was subtracted from each of seven observations the following numbers resulted in -3,0,-2,4,6,1,1. THE MEAN OF THIS DISTRIBUTION IS

Answer 1

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. THANK YOU... PLEASE MARK AS BRAINLIEST ANSWER!
