The lengths of text messages are normally distributed with a
population standard deviation of 5 characters and an unknown
population mean. If a random sample of 26 text messages is taken
and results in a sample mean of 24 characters, find a 92%
confidence interval for the population mean. Round your answers to
two decimal places. z0.10 z0.05 z0.04 z0.025 z0.01 z0.005 1.282
