4. In a study of caffeine and stress, college students indicate how many cups of coffee they drink per day and their stress level on a scale of 1 to 10 (with higher scores indicating greater stress). Data is collected from a sample of 10 students. The Pearson correlation coefficient for the relationship between these 2 variables is r = .43.

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...

. Average coffee consumption among graduate students is commonly known to be 3.89 cups per day. A graduate student took a sample of 10 fellow graduate students in her statistics class, and in the sample produced a mean of 4.02 cups per day and a standard deviation of .19. Because of this, she believes that the average is actually greater than what is commonly thought (3.89 cups per day). Do we believe the graduate student’s claim or the common belief?...
