a) Construct a stem-and-leaf display for the data set. You can simply type it below or use StatCrunch by entering the raw data (all 27 data values) into StatCrunch. Go to Graph > Stem
and Leaf. Be sure to titi and label your graph! (if you choose to use StatCrunch, be sure to correct any formatting issues after you paste your graph.)
b) Based upon the stem-and-leaf display, identify any distinctive features of the distribution of grams of fat in fast food items. Be sure to include the shape of the distribution.
c) Construct a grouped frequency distribution of the grams of fat data using Os x < 10 as the first class (table below) and determine (1) the class midpoint (class mark) for each
class. (You may use the Insert/Edit Table option on the bottom row of the editor to create your table.)
