A market researcher wants to study the television viewing habits of a particular small city. A sample of 40 adult residents is asked to record their television viewing in one week. The results are:
Viewing time: = 15.3 hours, S = 3.8 hours.
27 respondents watched the evening news every weeknight.
Suppose that a national census later finds that the national average amount of television watched by adults is 16.1 hours per week, and that 48.7% watch the national news every weeknight. In what ways, if any, does this particular city differ from the nation as a whole in its viewing habits? Justify your answer?
