Find a 90% confidence interval for the true mean caffeine content for the coffee manufactured by this company. 2. Interpret the above calculated interval in the context of the problem. 3. Use the intervalc ed in part 1 to test the hypothesis "if true mean caffeine content is different from 1 - Consider 10 % significance level to draw the conclusion. Your answer should clearly explain how the interval in part 1 lead you to the conclusion for the hypothesis test. Edit View Insert Format Tools Table RT U AV DV Try
