Question

THE MEAN OF 6 OBSERVATION IS 25 .
IF 4 IS ADDED TO EACH OBSERVATION ,THEN THE MEAN OF THE NEW DATA SET IS

Answer 1

Answer:

29

Step-by-step explanation:

= > Mean of 6 obs. = 25

= > (sum of 6 obs.)/6 = 25

= > sum of 6 obs. = 25*6 = 150

When 4 added to each term, it meant 4 is added 6 times, so added number = 4 + 4 + 4 + 4 + 4 + 4 = 4*6 = 24

New sum = 150 + 24 = 174

Thus,

Average = 174/6

Average = 29
