To determine the bin size, we need to divide the range of data by the number of bins. Looking at the histogram, we can see that the range of data is from 10 to 33, and there are approximately 8 bins. Therefore, the bin size would be:
Range of data/number of bins = (33-10)/8 = 2.875
Since we cannot have a fractional interval for the bins, we need to round up to the nearest whole number, which is 3. However, this would result in bins that do not align with the data values. Therefore, the best choice would be to round up to the next convenient number, which is 4. This would result in bins of 10-13, 14-17, 18-21, etc., which align with the data values and give a clearer picture of the distribution.
