Problem
The accompanying table gives the number of copies sold for 30 top-selling novels. Use data given in the table to construct a frequency distribution with a first class (in millions) of $0-99$. \begin{tabular}{ccc} Copies Sold (millions) \\ 500 & 90 & 70 \\ 300 & 87 & 65 \\ 150 & 85 & 65 \\ 150 & 85 & 60 \\ 130 & 85 & 45 \\ 103 & 80 & 45 \\ 100 & 80 & 40 \\ 100 & 75 & 40 \\ 100 & 70 & 40 \\ 100 & 70 & 30 \end{tabular} Construct a frequency distribution. Copies Sold (millions) Number of Books \[ \begin{array}{l} 0-99 \\ \square-\square \\ \square-\square \\ \square-\square \\ \square-\square \\ \square-\square \end{array} \]
Solution
Step 1 ：Determine the range of the data: 500 - 30 = 470
Step 2 ：Choose a width for each interval, such as 100
Step 3 ：Construct the frequency distribution table with the given intervals
Step 4 ：Count the number of values that fall into each interval
Step 5 ：Fill in the frequency distribution table with the counts
Step 6 ：The frequency distribution table is as follows: Copies Sold (millions) Number of Books 0-99 6 100-199 4 200-299 1 300-399 2 400-499 1
