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 50 - 99. Copies Sold (millions) 500 98 80 200 90 80 200 90 80 160 90 72 150 90 70 150 90 70 100 90 70 100 90 60 100 80 50 100 80 50 Construct a frequency distribution. Copies Sold (millions) Number of Books 50 - 99

Publishing Exercises $37-46$ are based on the following table, which shows the results of a survey of 100 authors by $a$ (fictitious) publishing company: $$ \begin{array}{r|c|c|c} & \begin{array}{c} \text { New } \\ \text { Authors } \end{array} & \begin{array}{c} \text { Established } \\ \text { Authors } \end{array} & \text { Total } \\ \hline \text { Successful } & 5 & 25 & 30 \\ \hline \text { Unsuccessful } & 15 & 55 & 70 \\ \hline \text { Total } & 20 & 80 & 100 \\ \hline \end{array} $$Compute the relative frequencies of the given events if $a n$ author as specified is chosen at random. An author is established.
