Refer to the Decision Analytics (October 2015) study of the features of Apple's iPhone 6, Exercise 2.13. Recall that opinions were extracted from a sample of 552 tweets obtained from the social media site Twitter.com. The tweets originated in four cities: San Francisco (138 tweets), New York (182), Los Angeles (89), and Chicago (143). A summary of the opinions on the iPhone 6 camera (Excellent, Good, or Bad) from tweets in each city is reproduced below. Conduct a test to compare the opinions on the iPhone 6 camera for tweets originating in the four cities. Is there evidence to conclude that the distribution of excellent, good, and bad opinions differs depending on the city? Use α = .05.
