100 students take a test in 2018. The average score was 75 and the standard deviation of the final exams scores was 5. The following year (2019), the professor changed her teaching style, and then taught the class to 90 students, gave the same exam, and found an average score of 80 and a standard deviation of 8.. Compute the 95% confidence interval for the final exam score in ECON 540 for 2018. Interpret the interval.
A laboratory tested 82 chicken eggs and found that the mean amount of cholesterol was 228 milligrams with a standard deviation of 19 milligrams. Construct a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs. (Provide the lower limit of the confidence interval as the answer below, rounding to the nearest whole number).
A simple random sample from a population with a normal distribution of 97 body temperatures has x=98.20°F and s=0.63°F. Construct a 99% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
A nutritionist selected a random sample of n = 50 adult males. The average daily intake of dairy products was found to be x (bar above) = 756 grams per day, with a standard deviation of s = 35 grams per day. Use this sample information to construct a 95% confidence interval for the mean daily intake of dairy products for men.

A researcher collected sample data for 15 middle-aged women. The sample had a mean serum cholesterol level (measured in milligrams per one hundred milliliters) of 192.7, with a standard deviation of 6. Assuming that serum cholesterol levels for middle-aged women are normally distributed, find a 99% confidence interval for the mean serum cholesterol level of all women in this age group. Give the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
