A quality control specialist for a restaurant chain takes a
random sample of size 10 to check the amount of soda served in the
16 oz. serving size. The sample mean is 13.60 with a sample
standard deviation of 1.54. Assume the underlying population is
normally distributed.
Find the 95% confidence interval for the true population mean for
the amount of soda served. (Round your answers to two decimal
places.)

A quality control specialist for a restaurant chain takes a random sample of size 10 to check the amount of soda served in the 16 oz. serving size. The sample mean is 13.20 with a sample standard deviation of 1.51. Assume the underlying population is normally distributed. Find the 95% confidence interval for the true population mean for the amount of soda served.
A chain restaurant wants to estimate the population mean weight of one of their entrees. A random sample size n = 36 showed sample mean = 18 ounces with sample standard deviation s = 1.8 ounces. Create a confidence interval at 95% confidence for the population mean μ.
A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x overbar, is found to be 108, and the sample standard deviation, s, is found to be 10.

(c) Construct a 70% confidence interval about mu if the sample size, n,...
A simple random sample of size n=20 is drawn from a population that is normally distributed with o = 11. The sample mean is found to be x = 59. Construct a 95% confidence interval about the population mean. The 95% confidence interval is . (Use ascending order. Round to two decimal places as needed.)
