 Solution The mean of 10 observations is 35 . While calculating the mean two observations were by mistake taken as 35 instead of 25 and 30 instead of 45 . Find the correct mean.Solution:Your problem -> The mean of 10 observations is 35 . While calculating the mean two observations were by mistake taken as 35 instead of 25 and 30 instead of 45 . Find the correct mean.Here Mean X = 35 and n = 10Sigma X = X × n = 35 × 10 = 350:. the correct sum Sigma X = 350 - 35 + 25 - 30 + 45 = 355.:. text{correct mean} = text{correct sum}/n = 355/10 = 35.5 .
