The one-sample z test is only appropriate for quantitative variables or variables that at least approximate interval level characteristics. Qualitative variables measured on an ordinal level cannot be analyzed with a one-sample z test. Additionally, knowing the population standard deviation is not a condition for using the one-sample z test.
