Assume that the fat content of chocolate donuts is normally distributed with population standard deviation 2.3 gram. A random sample of 130 donuts is selected for testing. The mean fat content of this sample is 26.3 gram. Estimate the true mean fat content of chocolate donuts by constructing the 99% confidence interval. Show your relevant steps below. Intermediate Calculations: z value = (Enter the number.) Standard Error = (cm) - (cm) Maximum Error of Estimate = Final Answer: The 99% Confidence Interval of the true mean fat content of chocolate donuts is (Lower Limit, Upper Limit) =( gram, gram) Notes: 1) Keep at least five significant figures for all

Question
Assume that the fat content of chocolate donuts is normally distributed with population standard deviation 2.3 gram. A random sample of 130 donuts is selected for testing. The mean fat content of this sample is 26.3 gram. Estimate the true mean fat content of chocolate donuts by constructing the 99% confidence interval. Show your relevant steps below. Intermediate Calculations: z value (Enter the number.) Standard Error = (om) Maximum Error of Estimate = (cm) Final Answer: The 99% Confidence Interval of the true mean fat content of chocolate donuts is (Lower Limit, Upper Limit) gram, gram) Notes: 1) Keep at least five significant figures for all intermediate values and your final confidence interval. Do not round your confidence interval. 2) This question will attempt to give you partial marks for later parts if they follow correctly from earlier calculations. For example, you may find that your z-value and standard error are marked incorrect, but the maximum error is marked correct. This may be because it follows correctly from the earlier (incorrect) values. To receive full marks on a subsequent attempt, you will need to correctly re-calculate all values.
