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 {Probability value, Z test statistic}.
ZMeanTest[ <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 {Probability value, Z test statistic}.
