The table below gives information about the weight, w w\,w kg, of 30 parcels in a delivery van.
| Weight (w w\,w kg) | Frequency |
|---|---|
| 0<w≤20 < w \leq 20<w≤2 | 5 |
| 2<w≤42 < w \leq 42<w≤4 | 12 |
| 4<w≤64 < w \leq 64<w≤6 | 8 |
| 6<w≤106 < w \leq 106<w≤10 | 5 |
Find the class interval that contains the median weight.
Work out an estimate for the mean weight of the parcels.
