Question
The length of time (in months) between the onset of a particular illness and its recurrence was recorded for n = 50 patients. 2.4 4.4
The length of time (in months) between the onset of a particular illness and its recurrence was recorded for
n= 50
patients.
2.4 | 4.4 | 2.7 | 32.3 | 9.0 | 9.0 | 2.0 | 6.6 | 3.9 | 1.6 |
14.7 | 10.1 | 16.7 | 7.4 | 8.2 | 19.2 | 6.9 | 4.3 | 3.3 | 1.2 |
4.1 | 18.4 | 0.2 | 6.1 | 13.5 | 7.4 | 0.2 | 8.3 | 0.3 | 1.3 |
15.8 | 1.0 | 2.4 | 2.4 | 18.0 | 8.7 | 24.0 | 1.4 | 8.2 | 5.8 |
1.6 | 3.5 | 11.0 | 18.0 | 26.7 | 3.7 | 12.6 | 23.1 | 5.6 | 0.1 |
(a)Construct a relative frequency histogram for the data.
A histogram has a horizontal axis labeled "Length of Time (months)" with values from 0 to 33 and a vertical axis labeled "Relative Frequency" with values from 0 to 0.3. The histogram has 10 bars of equal width. Each bar is associated with an interval and an approximate value as listed below.
- 0 to 3: 0.04
- 6 to 9: 0.08
- 9 to 12: 0.14
- 12 to 15: 0.16
- 15 to 18: 0.24
- 18 to 21: 0.14
- 21 to 24: 0.1
- 24 to 27: 0.04
- 27 to 30: 0.04
- 30 to 33: 0.02
(b)Would you describe the shape as roughly symmetric, skewed right, or skewed left?
