A shopkeeper recorded the weight, w w\,w kg, of 50 pumpkins sold at a farm shop. The table shows information about the weights.
| Weight (w w\,w kg) | Frequency |
|---|---|
| 0<w≤20 < w \leq 20<w≤2 | 10 |
| 2<w≤42 < w \leq 42<w≤4 | 15 |
| 4<w≤54 < w \leq 54<w≤5 | 12 |
| 5<w≤75 < w \leq 75<w≤7 | 8 |
| 7<w≤117 < w \leq 117<w≤11 | 5 |
Calculate an estimate for the mean weight of the pumpkins.
