Spa Satisfaction 5. Spa services, such as massages, facials, and wellness therapies, contribute to passenger relaxation and overall cruise enjoyment. To evaluate the quality of the spa services across three ships of differing classes, Holland America Line administers a survey asking passengers rate their overall satisfaction with the spa services on a scale from 1 to 100, with 100 representing the highest level of satisfaction. Data are or the SPA tab. The ships are the MS Koningsdam (Pinnacle-class), MS Nieuw Amsterdam (Signature-class), and the MS Westerdam (Vista-clan., What is the appropriate statistical test for these data?
