A student repeated an experiment five times to measure the highest temperature reached during the displacement reaction between magnesium powder and copper(II) sulfate solution.
The table below shows the results of the five trials:
| Trial | Highest temperature reached (∘C^\circ\text{C}∘C) |
|---|---|
| 1 | 41.8 |
| 2 | 41.3 |
| 3 | 42.1 |
| 4 | 41.6 |
| 5 | 41.7 |
Calculate the mean highest temperature reached and its associated uncertainty.
State your final answer in the form: mean±uncertainty\text{mean} \pm \text{uncertainty}mean±uncertainty.
