Chapter 9 Exercise 1212. The American Sugar Producers Association wants to guess the toy with yearly sugar consumption. A sample of 16 people reveals the conceive yearly consumption to be 60 pounds with a standard deviation of 20 pounds. A. What is the value of the rural argona mean? What is the shell estimate of this value? arrange: The population mean is unknown because the sum of the values is not known. The outstrip estimate is 60 pounds, which is also the sample mean. The population mean is the sum of all the values in the population burst by the number of values in the population. B. Explain why we pauperisation to use the t scattering. What assumption do you privation to make? settlement: We need to use the t distribution because the standard deviation is unknown and the sample size is pocket-sized than 30. I would need to make a normality assumption. C. For a 90 percent combine musical interval, what is the value of t?Answer: N-1 = 15, which gives a value of df of 15. Using the 90% interval t is equal to: 1.753D. Develop the 90 percent confidence interval for the population mean. Answer:X ± t S which equals: 68.765 and 51.235?nX = 60, t = 1.753, S = 20, n = 16. The endpoints for the confidence interval are: 68.765 for the velocity confidence limit and 51.

235 for the lower confidence limit. E. Would it be middling to conclude that the population mean is 63 pounds?Answer: Yes it would be reasonable to conclude that the population mean is 63 pounds because it waterfall between the 68.765 and 51.235 intervals.
