ABSTRACT

Directions: Convert the frequencies to percents and plot the percents with the corresponding midpoints of the intervals on graph paper. Use a solid line for School A and a dashed line for School B. Make each curve begin and end at zero percent by plotting the midpoints of one interval above and one interval below those shown on this page. To find the answer to the riddle, write "T" for "true" or "F" for "false" on the line to the left of each statement. The word at the end of the first true statement is the first word in the answer to the riddle, the word at the end of the second true statement is the second word, and so on.
