- TTest( <List of Sample Data>, <Hypothesized Mean>, <Tail> )
- Performs a one-sample t-test of a population mean using the given list of sample data. 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, t-test statistic}.
- Example:
TTest({1, 2, 3, 4, 5}, 3, "<")yields {0.5, 0}.
- TTest( <Sample Mean>, <Sample Standard Deviation>, <Sample Size>, <Hypothesized Mean>, <Tail> )
- Performs a one-sample t-test of a population mean using the given sample statistics. Hypothesized Mean and Tail are defined as above. Results are returned in list form as {Probability value, t-test statistic}.
- Example:
TTest(4, 1, 12, 4, "≠")yields {1, 0}.
