Harbucks coffee claims that the average amount of caffeine in cups of their coffee is 180 mg. Randy wishes to check the validity of this claim, and so he obtains a random sample of 49 cups of Harbucks coffee, from which he obtains a sample mean and standard deviation of 181 mL and 1.2 mL. Randy also notes that the sample data exhibit strong right skewness, so he suspects the population is also right skewed Does Randy have evidence to...
