1. **State the problem:** We are given the number of missions completed by 15 soldiers in a month: 1, 2, 3, 4, 2, 3, 4, 5, 1, 2, 3, 4, 2, 3, 4. We need to construct a frequency table showing how many soldiers completed each number of missions. 2. **List the data:** The data points are: 1, 2, 3, 4, 2, 3, 4, 5, 1, 2, 3, 4, 2, 3, 4. 3. **Identify unique values:** The unique mission counts are 1, 2, 3, 4, and 5. 4. **Count frequencies:** - Number of soldiers who completed 1 mission: count how many times 1 appears. - Number of soldiers who completed 2 missions: count how many times 2 appears. - Number of soldiers who completed 3 missions: count how many times 3 appears. - Number of soldiers who completed 4 missions: count how many times 4 appears. - Number of soldiers who completed 5 missions: count how many times 5 appears. 5. **Calculate frequencies:** - For 1 mission: appears 2 times. - For 2 missions: appears 4 times. - For 3 missions: appears 4 times. - For 4 missions: appears 4 times. - For 5 missions: appears 1 time. 6. **Construct the frequency table:** | Missions Completed | Frequency | |--------------------|-----------| | 1 | 2 | | 2 | 4 | | 3 | 4 | | 4 | 4 | | 5 | 1 | This table summarizes the number of soldiers completing each number of missions.
