A sample of 80 juvenile salmon is grouped into the resulting frequency distribution based on their weights.
| Weight (in grams) |
Frequency |
| 100-149 |
15 |
| 150-199 |
10 |
| 200-249 |
30 |
| 250-299 |
25 |
If a Pie Chart were constructed for the weights of the salmon, what would be the measure of the central angle for the class weighing 200-249 grams?
