Question

Mean of eight observations is 25. If one observation 11 is excluded, find the mean of the remaining​

Answer 1

Answer:

Total = 25x8=200

excluded 11=189

mean of the remaining=189 / 7 = 27

Answer 2

Answer-27

Step-by-step explanation:

x/8=25

x=200

Now,

x-11/7=y

200-11/7=y

189/7=y

y=27

y is the mean of remaining

Henceforth 27 is the mean of remaining
