Given the ratio 5 : 4:
Calculate the
expected number of items from a population of 110
Ratio Definition
5 : 4 means that for every
Therefore, our total group is 5 + 4 = 9
Calculate Expected Number of Item A:
| Expected Number of Item A = | 5 x 110 |
| 9 |
| Expected Number of Item A = | 550 |
| 9 |
Calculate Expected Number of Item B:
| Expected Number of Item B = | 4 x 110 |
| 9 |
| Expected Number of Item B = | 440 |
| 9 |
Final Answer
Expected Number of Item A = 0
Expected Number of Item B = 0
Expected Number of Item B = 0
