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?
