Alaboratory tested 85 chicken eggs and found that the mean amount of cholesterol was 190 milligrams. assume that the sample standard deviation is 11.7 milligrams. construct a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs. state your conclusion in a statistical sentence.

Step-by-step explanation:

Given : Significance level :

Sample size : n=85

Critical value :

Sample mean :

Standard deviation :

The confidence interval for population mean is given by :-

Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs =

Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.

yes
