The lengths оf text messаges аre nоrmаlly distributed with a pоpulation standard deviation of 3 characters and an unknown population mean. A random sample of 16 text messages is taken. The sample mean was 37 characters. Provide the following parameters and compute the 95% confidence interval: (overline{X}) (sigma) (n) (z_{alpha / 2} ) The confidence interval (given in interval notation) As a reference, here are some common values for (z). (z_{0.10}=1.282) (z_{0.05}=1.645) (z_{0.025}=1.960) (z_{0.01}=2.326) (z_{0.005}=2.576)
