The International Coffee Association has reported the mean daily coffee consumption for U.S. residents as 1.65 cups.Assume that a sample of 38 people from a North Carolina city consumed a mean of 1.84 cups of coffee per a day, with a standard deviation of 0.85 cups. In a two- tail test at the 0.05 level, could the residents of this city be said to be signifificantly different from their counter-parts across the nation?
