Ans:
We know that for normal distribution:
IQR=Q3-Q1=1.349*s
| Q1 | Q3 | s | IQR=Q3-Q1 | 1.349*s | |
| A | 1330 | 2940 | 2440 | 1610 | 3291.56 |
| B | 105 | 270 | 33 | 165 | 44.517 |
| C | 14 | 68 | 41 | 54 | 55.309 |
| D | 2.2 | 7.3 | 2.1 | 5.1 | 2.8329 |
Option C is correct,as IQR is approximately 1.349*s
