Consider the data set below.

3.4	5.0	2.6	3.9	2.4	4.4	3.5	4.0	4.1	4.6
2.6	2.3	3.1	3.6	3.7	2.9	3.6	4.2	4.0	4.1
3.6	6.1	2.3	3.0	2.8	5.2	1.7	5.9	2.1	3.4
2.2	3.7	5.5	4.6	1.6	3.9	6.3	4.7	3.7	4.0
4.2	5.9	3.7	5.0	3.9	5.8	4.9	4.2	3.4	3.9

Construct a relative frequency histogram for these 50 measurements using classes starting at 1.6 with a class width of 0.5.

A relative frequency histogram has a horizontal axis with values from 1.1 to 7.0 and a vertical axis labeled "Relative Frequency" with values from 0.00 to 0.40. The relative frequency histogram has 10 bars of equal width. Each bar is associated with an interval and a value as listed below.

• 1.6 to 2.1: 0.04
• 2.1 to 2.6: 0.10
• 2.6 to 3.1: 0.04
• 3.1 to 3.6: 0.10
• 3.6 to 4.1: 0.28
• 4.1 to 4.6: 0.06
• 4.6 to 5.1: 0.10
• 5.1 to 5.6: 0.04
• 5.6 to 6.1: 0.12
• 6.1 to 6.6: 0.12

How would you describe the shape of the distribution?
