An enterprising art historian recently started a new business: the production of walking-tour audiotapes for use by those visiting major cities. She originally produced tapes for eight cities: Paris, Rome, London, Florence, Jerusalem, Washington, New York, and New Haven.
A test was carried out to determine whether all eight tapes (featuring different aspects of different cities) were equally appealing to potential users. A random sample of 160 prospective tourists was selected, 20 per city. Each person evaluated the tape he or she was given on a scale of 0 to 100.
The results were analyzed using one-way ANOVA and included SSTR = 7,102 and SSE = 10,511. Are all eight tapes equally appealing, on average? What can you say about the p-value?
