Explanation of Solution
Given:
Table is:
Quadrant | Frequency |
1 | 18 |
2 | 22 |
3 | 39 |
4 | 21 |
The proportions are
Calculation:
Here, the smallest probability is 1/8, thus it would be used to compute the frequency.
The expected frequencies are calcualted as:
Here, conditions are fulfilling for (d) and (e) but the smallest
Thus, the correct option is (d).
