Q1) Enterprising art historian just started new business: the production of walking tour audiotapes for use by those visiting major cities. She initially produced tapes for eight cities: paris , Rome. London, Florence, Jerusalem, Washington, New York, new haven. A test was performed to find out whether all 8 tapes (featuring various aspects of different cities) were evenly appealing to potential users. A random sample of 60 prospective tourists was chosen, 20 per city. Each person estimated tape he or she was given on the scales of 0 to 100. Results were analyzed using one -way ANOVA and included SSTR =7 , 102 and SSE = 10 ,511. Are all 8 tapes equally appealing on average? Determine p value?
