A sample was taken of the verbal test scores of 20 applicants to graduate school at a large midwestern university. Below are the scores. For convenience, the data are ordered. 280 310 340 350 380 400 420 420 420 430 510 510 520 520 600 610 670 720 750 770 (All answers should be exact calculations.) a) The median is b) The first quartile is c) The third quartile is d) The IQR is e) The lower fence is f) The upper fence is || g) Is/Are there any outlier(s)? Both 280 and 770 are outliers. The value 280 is an outlier. The value 770 is an outlier. Both 750 and 770 are outliers. There are no outliers. h) If 25 points were added to each score, what happens to the resulting standard deviation of the new scores? It cannot be determined. It would increase by 25. It would be unchanged. It would increase by 625. ○ It would increase by 5.
