do a chi-square test at a= 0.025. use 8 bins to define bins by using method 3. Find p value
Expert Solution
Step1
Calculation of Bins
Minimum value=12.60 . We take it as 12.
Maximum value=47.64. We take it as 48.
Range=Max value- Min value=48 -12=36.
We have to take 8 bins. So let's divide 36 by 8 to get the bin size and we will get 4.5.
Now we can take the bins as 12-16.5, 16.5-21, 21-25.5, 25.5-30,........, 43.5-48.
The Frequency distribution is given as below:
| Bins | Frequency |
| 12-16.5 | 9 |
| 16.5-21 | 7 |
| 21-25.5 | 5 |
| 25.5-30 | 4 |
| 30-34.5 | 5 |
| 34.5-39 | 4 |
| 39-43.5 | 3 |
| 43.5-48 | 5 |
| Total | 42 |
