Unit 16 Data Presentation Histograms with Unequal Class

You can not draw histograms with equal intervals as the data is not given in this way. So for each of the intervals, you need to give: Weight (grams)Frequency 0 ≤ w < ≤ w < ≤ w < ≤ w < ≤ w < 1002 Weight (grams)FrequencyFrequency Density 0 ≤ w < ≤ w < ≤ w < ≤ w < ≤ w < 1002 Now you can draw the histogram
