Question

when the outliers are removed how does the mean change? (2 points) dot plot with 1 on 18 2 on 38 1 on 40 3 on 44 1 on 46 1 on 48 the mean decreases by 2.75. the mean increases by 2.75. the mean increases by 3.25. there are no outliers.

Answer 1

The correct answer for this question is 2.75

18,38,38,40,44,44,44,46,48

If we calculate the mean for this it would be 40 (360/9) (this one is included)

38,38,40,44,44,44,46,48

If we calculate the mean for this it would be 38 (360 - 18) / 9 = 342/9 (this one is excluded)
