Michael recorded the maximum temperature every day in September. The table shows information about his results.
| Temperature (∘C^{\circ}\text{C}∘C) | Frequency |
|---|---|
| 14<t≤1814 < t \leq 1814<t≤18 | 4 |
| 18<t≤2018 < t \leq 2018<t≤20 | 10 |
| 20<t≤2220 < t \leq 2220<t≤22 | 8 |
| 22<t≤2422 < t \leq 2422<t≤24 | 5 |
| 24<t≤2824 < t \leq 2824<t≤28 | 3 |
