Cont. from the previous question

The demand for the printed catalog is distributed as follows $($a selective part$)$:

Number of Catalogs $...60616263646566...$

Cumulative Probability $...0\mathrm{.}800\mathrm{.}830\mathrm{.}860\mathrm{.}890\mathrm{.}910\mathrm{.}930\mathrm{.}94...$

Please identify the optimal production quantity, i$.$e$.,$ the number of catalogs to be printed, based on the optimal service level identified in the previous question. Please explain your logic to show the work.
