Use the data in the table below to complete parts (a) through (c). 15 16 19 46 40 42 34 21 23 24 24 40 Click the icon to view the steps for finding influential points. = (a) Construct a scatterplot of the data. Choose the correct graph below. O A. O B. OD. So try - (b) Identify any possible outliers. O A. The point (46,6) may be an outlier. OB. The point (6,34) may be an outlier. O C. The point (19,24) may be an outlier. O D. The point (6,40) may be an outlier. O E. There are no outliers. (c) Determine if the point is influential. The change in slope or intercept is significant if it is larger than 10%. v an influential point because the slopes with the point included and without the point included V significantly different, and the intercepts v significantly The point different.

Explanation / Answer

(a) B is the correct scatterplot

(b) A. The point (46,6) might be an outlier

(c) The point (46,6) is not influential.
