Mr. Li records the measures of the lengths of his students’ handprints. The lengths, in centimeters, are shown in the table.
A 7-column table with 3 rows. The first row contains entries 14.0, 11.5, 12.1, 16.2, 13.5, 14.3, 16.8. The second row contains entries 12.4, 13.7, 12., 14.7, 15.2, 11.9, 15.6. The third row contains entries 13.8, 14.2, 12.5, 15.0, 16.0, 13.1, 11.7.
If the class creates a histogram of the data in the table, how many students are in the range 12 cm to 13.9 cm?
