For a distribution of 250 heights, calculations showed that the mean, standard deviation 1 and 2 were 54 inches, 3 inches, 0 inches and 3 inches. It was however, discovered on checking that two items 64 and 50 in the original data were wrongly written in place of the correct values 62 and 52 inches respectively. Calculate the correct frequency constant( new mean, new variance, new 1, new 2).
