73. The dividend yield for five hypothetical companies is given below:
| Paknama | 10.5% |
| Genie Ltd. | 16.25% |
| Mirinda Corp. | 27.0% |
| Tina Travels Ltd. | 12.0% |

The population variance is closest to:
- Option : B
- Explanation : Use the following keystrokes to calculate the population variance: [2nd] [DATA] [2nd] [CLR WRK] X01 = 10.5 X02 = 16.25 X03 = 27 X04 = 12 X05 = 7.8 Choose the population standard deviation: σ = 6.723. Then square it, to get population variance as 45.2.
