Question
**Problem Statement: Confidence Interval Estimation** Bob draws a simple random sample from an original population where the standard deviation is known to be \( \sigma = 12 \). The sample size is \( n = 75 \) and the sample mean turns out to be \( \bar{x} = 43 \). Find the 99% confidence interval for the population mean \( \mu \). **Answer Choices:** A. \( (33.431, 40.569) \) B. \( (35.431, 42.569) \) C. \( (37.431, 44.569) \) D. \( (39.431, 46.569) \) The task is to determine which of the provided options correctly represents the 99% confidence interval for the given sample data.
