    Okay so first put all of those values into a stem and leaf diagram -from there you can find the mode and median easily.. There are 50 terms so the mean is the sum of them divided by 50 -which i believe is 34.98 (x-bar) Then the freqeuncy table will have your class widths in the left column and the and the frequency on the right -I would suggest you have class widths of \[0\le x <10\] \[10\le x <20\] and so on.. For the histogram it looks like a bar chart but you can have different class widths, this isn't really necessary as the said you can choose them frequency goes on the y-axis. I don't understand the other parts of the question so i can't help you with that... hope i've helped!
