Determine if the outcome is unusual. Consider as unusual any result that differs from the mean by more than 2 standard deviations. That is, unusual values are either less than μ - 2σ or greater than μ + 2σ. 12) A recent coffee consumption study showed that among 1253 randomly selected subjects, 80% of them drank coffee every day. For such group of 1253 subjects, would it be significantly high to obtain 1005 coffee drinkers?
