A coffee company claims that the amount of caffeine for one cup of their brand of espresso is 210 mg. Caffeine content for this brand of espresso is known to follow a normal distribution with standard deviation 37 mg. We will select a random sample of 18 cups of espresso and conduct a hypothesis test at the 10% level of significance to determine whether the true mean caffeine content of all brands of espresso differ from 210 mg.. At the 10% level of significance the power of the test that the true mean caffeine content is 218 mg is 0.2379. Using the same level of significance (10%), what is the power of the test that the true mean caffeine content is 202 mg? 0.4444 0.3727 0.2379 0.0052 0.1829
