Suppose weights of running shoes are normally distributed and have a known population standard deviation of 1 ounces and an unknown population mean. A random sample of 24 running shoes is taken and gives a sample mean of 13 ounces. Identify the parameters needed to calculate a confidence interval at the 80% confidence level. Then find the confidence interval. z0.10 z0.05 z0.025 z0.01 z0.005
1.282 1.645 1.960 2.326 2.576
You may use a calculator or the common z values above.
