Use the data in the table below to complete parts (a) through (c). 4 25 7 39 9 29 X y Click the icon to view the steps for finding influential points. -12- · 50 (b) Identify any possible outliers. A. The point (4,25) may be an outlier. B. The point (7,39) may be an outlier. C. The point (43,6) may be an outlier. O D. The point (19,21) may be an outlier. E. There are no outliers. 50- 0+ 0 40 10 28 15 28 40+ 0- 0 X 50 16 22 (c) Determine if the point is influential. The change in slope or intercept is significant if it is larger than 10%. The point ▼an influential point because the slopes with the point included and without the point included significantly different. 19 21 124 -12- 1 43 6 40 Q significantly different, and the intercepts
