Expert Solution

Problem with using classes of 0-30, 30-60,...,120-150

The problem with using classes of 0-30, 30-60, ..., 120-150 for this frequency distribution is that the classes have unequal widths. The first class (0-30) has a width of 30, but the other classes all have a width of 31 (except for the last class, which has a width of 31 as well, but only contains 8 observations). This can lead to distortion in the data and make it difficult to accurately represent the distribution.
