To find the best cell interval, we need to consider factors such as the overall range of the data and the desired number of intervals. A general rule of thumb is to have between 5-20 intervals.

In this case, the range of the data is 360 kg - 295 kg = 65 kg. To get a cell interval that is easy to work with mathematically and visually, we should choose a number that divides evenly into the range.

Out of the given choices, only 5 divides evenly into 65 (65/5 = 13). Therefore, the best choice would be 5. This would give us a total of 13 intervals, which is a reasonable number for 400 observed values.
