Directions: In 1-8, use the frequency table that follows. It displays the results of a survey where an SRS of size 200 college professors submitted their number of grandchildren. | Grandchildren | Frequency (f) | Midpoint (x) | Positions | | :--- | :--- | :--- | :--- | | 0-3 | 60 | 1.5 | x1 to x60 | | 4-7 | 40 | 5.5 | x61 to x100 | | 8-11 | 50 | 9.5 | x101 to x150 | | 12-15 | 25 | 13.5 | x151 to x175 | | 16-19 | 12 | 17.5 | x176 to x187 | | 20-23 | 10 | 21.5 | x188 to x197 | | 24-27 | 3 | 25.5 | x197 to x200 | | SUM | 200 | n/a | n/a | 1) What is the modal class of this dataset? A. 0-3 B. 4-7 C. 8-11 D. 12-15 E. None of these
