1. A laboratory tested 87 chicken eggs and measured the mean amount of cholesterol to be \bar{x} = 266 mg. Assume that the population standard deviation is known to be $\sigma = 16$ mg a. Why are we allowed to assume that the sampling distribution in this problem is normal? Because the population is normal. b. Construct a 90% confidence interval for the true mean cholesterol content of all such eggs. Round to two decimal places. Interpret the result in the context of the problem. c. How many eggs must be sampled to obtain a 90% confidence level with a margin of error E = 1.5 for the mean cholesterol content? Round up to the nearest whole number.
