Question
I need part B only
Here is the solution of part a
A frequency distribution displays various outcomes in a sample. Frequency indicates the number of occurrences.
The inputs of a frequency table are-
- Class Boundaries
- Midpoint
- Frequency
The Frequency distribution for the given data is-
| Class boundary | Mid point | Frequency |
| 60-70 | 65 | 2 |
| 70-80 | 75 | 6 |
| 80-90 | 85 | 4 |
| 90-100 | 95 | 6 |
| 100-110 | 105 | 4 |
| 110-120 | 115 | 2 |
Each lower class boundary is included in that class and the Midpointupper-class boundary is included in the next class. But in the last class (110-120) upper class is included in that class.
