(d) Draw a relative-frequency histogram.

(e) Categorize the basic distribution shape.

a. skewed left
b. mound-shaped symmetrical    
c. bimodal
d. skewed right
e. uniform
 
(f) Draw an ogive.
(b) Make a frequency table showing class limits, class boundaries, midpoints, frequencies, relative frequencies, and cumulative frequencies. (Give relative frequencies to 2 decimal places.)
