This activity involves testing a hypothesis about a population mean, μ,μ, where σσ, the population standard deviation is unknown. We will test a hypothesis about the number of letters in students' last names. The claim is that the average number of letters in students' last names is less than 7. Assume that the population standard deviation, σ,σ, is not known and that s the sample standard deviation has to be calculated. students last names: Flores - 6 Zhang - 5 Vuong - 5 Figueroa - 8 Decide the significance level you are going to use to test. Determine the mean (average) and the standard deviation of the last names.
