Question

The mean of 5 observations is 89. If one of the observations is wrongly taken as 64 instead of 46, find the
correct mean

Answer 1

Answer:

Step-by-step explanation:

let the sum of observations be x+64

(x+64)/5=89

x+64=445

x=445-64=381

but it was misread as 64 instead of 46

x+46/5=381+46/5=427/5=85.4
