Answer: 
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.
