Question
Use the confidence level and sample data to find a confidence interval for estimating the population μ. Round your answer to the same number of decimal places as the sample mean.
A laboratory tested 83 chicken eggs and found that the mean amount of cholesterol was 233 milligrams with σ=12.9σ=12.9 milligrams. Construct a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs.
