A symmetric data distribution is shown. Which addition of data will have the greatest effect on the mean? A data set has a number line ranging from 1 to 15, with data points as follows: 4, 1; 5, 2; 6, 4; 7, 2; 8, 1. CLEAR CHECK The data set from the original problem with orange data points added above 4, 5, 6,7, and 8. The data set from the original problem with 3 orange data points added above 1. The data set from the original problem with an orange data point added above 8, and 3 orange data points added above 9. The data set from the original problem with 3 orange data points added above 15.
