Question
**Constructing a Grouped Frequency Distribution** To construct a grouped frequency distribution for the data provided, follow the instructions given. The data consists of the lengths, in miles, of 25 rivers. Use five classes of the same width. **Data List:** - River lengths (in miles): 2650, 2620, 1980, 1870, 1870, 1460, 1450, 1450, 1340, 1280, 1270, 1150, 1070, 970, 925, 911, 891, 859, 790, 770, 751, 717, 688, 660, 642. **Select the correct choice below and fill in any answer boxes within your choice:** **Option A:** - Length | Frequency - 500-999 | - 1000-1399 | - 1400-2099 | - 2100-2499 | - 2500-2999 | **Option B:** - Length | Frequency - 500-999 | - 1000-1499 | - 1500-1999 | - 2000-2499 | - 2500-2999 | **Option C:** - Length | Frequency - 500-899 | - 900-1499 | - 1500-1999 | - 2000-2299 | - 2300-3000 | Each option provides a different range for grouping the river lengths into classes. The goal is to determine the most appropriate ranges, ensuring equal class width to accurately represent the data's distribution.
