The above data show the weights of 120 boys. (Use graph paper (see my examples) to construct all your graphs, scan it and submit.)

Obtain a frequency table for the weights which should be of 11 classes, and should have the classes, class boundaries, class midpoints, frequencies, cumulative frequencies, relative frequencies and cumulative relative frequencies
Construct a frequency histogram of the data which is well labeled.
Construct a frequency polygon for the data.
Obtain the range for the weights
