Exercise 9-12 (Algo) (L09-1, LO9-2) The US Dairy Industry wants to estimate the mean yearly milk consumption A sample of 12 people reveals the mean yearly consumption to be 56 gallons with a standard deviation of 16 gallons. Assume the population distribution is normal. (Use Distribution Table & z Distribution Table) Required: a-1. What is the value of the population mean Unknown 56 16 0-2. What is the best estimate of this value? Estimated population mean 56
c. For a 99% confidence interval, what is the value of C (Round your answer to 3 decimal places.) Value of d. What is the margin of error? (Round your answer to 3 decimal places.) Margin of error e Develop the 99% confidence interval for the population mean (Round your answers to 3 decimal places.)
e. Develop the 99% confidence interval for the population mean (Round your answers to 3 decimal places.) Confidence interval for the population mean is between 45.834 and 66 166 f. Would it be reasonable to conclude that the population mean is 57 gallons? Yes NO It is not possible to tell
