A coffee manufacturer is interested in whether the mean daily
consumption of regular- coffee drinkers is less than that of
decaffeinated coffee drinkers. Assume the population standard
deviation for those drinking regular coffee is 1.21 cups per day
and 1.40 for those drinking decaffeinated coffee. A random sample
of 54 regular coffee drinkers showed a mean of 4.59 cups per day. A
sample of 49 decaffeinated coffee drinkers showed a mean of 5.64
cups per day.

healthier than coffee but coffee has more caffeine. Consumers have
decreasing marginal utility for both caffeine and health. However,
recent scientific results find that coffee is much healthier for
you than previously believed. Answer the following questions:
1. Show graphically and explain in 2-3 sentences how this
discovery impacts the equilibrium Price and Quantity in the
perfectly competitive coffee market.
