- ZMeanTest[ <List of Sample Data>, <Population Standard Deviation σ>, <Hypothesized Mean>, <Tail> ]
- Performs a one sample Z test of a population mean using the given list of sample data and the population standard deviation. Hypothesized Mean is the population mean assumed in the null hypothesis. Tail has possible values "<", ">" , "≠". These specify the alternative hypothesis as follows.
- "<" = population mean < Hypothesized Mean
- ">" = population mean > Hypothesized Mean
- "≠" = population mean ≠ Hypothesized Mean
- Results are returned in list form as {P value, Z test statistic}.
- ZTest[ <Sample Mean>, <Population Standard Deviation σ>, <Sample Size>, <Hypothesized Mean>, <Tail> ]
- Performs a one sample z test of a population mean using the given sample statistics and the population standard deviation. Hypothesized Mean and Tail are defined as above. Results are returned in list form as {P value, Z test statistic}.
