Miller (2008) examined the energy drink consumption of college undergraduates and found that males use energy drinks significantly more often than females. Assume that the overall level of consumption for college male undergraduates averages μ = 30 ounces of energy drinks per month , and that the distribution of monthly consumption scores is approximately normal with a standard deviation of σ = 14. To investigate this phenomenon, a researcher selects a random sample of n = 8 females and finds they drank an average of 16 ounces per month. Did this sample of females drink significantly fewer ounces of energy drinks than their male counterparts? What is the Z-score for the sample?
