Often, cruise ships conduct all on-board transactions, with the exception of gambling, on a cashless basis. At the end of the cruise, guests pay one bill that covers all on-board transactions. Suppose that 58 single travelers and 80 couples were surveyed as to their on-board bills for a seven-day cruise from Los Angeles to the Mexican Riviera. Below is a summary of the bills for each group. Singles Amount ($) 51-100 Frequency Relative Frequency 5 101-150 10 151-200 14 201-250 14 251-300 10 301-350 5 Couples Amount ($) Frequency Relative Frequency 100-150 6 151-200 6 201-250 6 251-300 6 301-350 11 351-400 11 401-450 11 451-500 11 501-550 6 551-600 6 Part (a) Fill in the relative frequency for each group.
