HELP Which answer correctly describes the change in the standard deviation for the data set {3,4,6,7,8,20} when the outlier is not included in the calculation? (Its Not The Second one.)

The standard deviation decreases from 8 to 5.6, which means a graph of the values is less spread out without the outlier.

The standard deviation is still 5.63, which means a graph of the values doesn't change without the outlier.

The standard deviation decreases from 5.63 to 1.85, which means a graph of the values is less spread out without the outlier.

The standard deviation increases from 1.85 to 5.63, which means a graph of the values is more spread out without the outlier.
