1. **Problem statement:** Organize the given birth rates data into a frequency distribution starting at 10 with intervals of 5. 2. **Formula and rules:** A frequency distribution groups data into intervals (classes) and counts how many data points fall into each interval. 3. **Step 1: Define class intervals starting at 10 with width 5:** - 10 to <15 - 15 to <20 - 20 to <25 - 25 to <30 - 30 to <35 - 35 to <40 - 40 to <45 - 45 to <50 - 50 to <55 4. **Step 2: Count data points in each interval:** - 10 to <15: values 10, 10, 12, 13, 14, 12, 10, 13, 13, 11 (10 values) - 15 to <20: values 15, 17, 19, 19, 19, 15, 16, 18, 16, 18, 17, 18, 15, 17, 18 (15 values) - 20 to <25: values 20, 22, 22, 20, 20, 24, 24 (7 values) - 25 to <30: values 25, 27, 27, 28, 28 (5 values) - 30 to <35: values 30, 31, 31, 31, 32, 32, 32, 33, 34, 34, 35, 35 (12 values) - 35 to <40: values 37, 38 (2 values) - 40 to <45: values 40, 42, 43, 44, 45 (5 values) - 45 to <50: value 50 (1 value) - 50 to <55: value 55 (1 value) 5. **Step 3: Present frequency distribution table:** | Class Interval | Frequency | |----------------|-----------| | 10 - 14 | 10 | | 15 - 19 | 15 | | 20 - 24 | 7 | | 25 - 29 | 5 | | 30 - 34 | 12 | | 35 - 39 | 2 | | 40 - 44 | 5 | | 45 - 49 | 1 | | 50 - 54 | 1 | This frequency distribution organizes the data clearly into intervals of 5 starting at 10.
