Question #4 An article in Food Testing and Analysis measured the sugar concentration (Brix) in clear apple juice. All readings were taken at 20°C: 11.48 11.45 11.48 11.47 11.48 11.50 11.42 11.49 11.45 11.44 11.45 11.47 11.46 11.47 11.43 11.50 11.49 11.45 11.46 11.47 (a) Test the hypothesis Ho:u=11.5 versus H1:µ#11.5 using a=0.05. Find the P-value. (b) Compute the power of the test if the true mean is 11.4. (c) What sample size would be required to detect a true mean sugar concentration of 11.45 if we wanted the power of the test to be at least 0.9?
