By how much does the mean of the data set below change if the outlier is removed round your answer to the nearest tenth if necessary 8,6,9,12,19,7,10,8

It changes by ~1.3

With outlier: add all terms-79 divide by # of terms (8) 79/8 = 9.875

Without outlier: add all terms except 19.60 divide by #of terms (7) 60/7=~8.5714

Subtract 9.875 - 8.7514 ... = ~1.306. Round to nearest 10th = 1.3
