ZInterval
ZInterval (one-sample z confidence interval; item 7) computes a confidence interval for an unknown
population mean m when the population standard deviation s is known. The computed confidence
interval depends on the user-specified confidence level.
In the example:
L1={299.4, 297.7, 301, 298.9, 300.2, 297}
TInterval
TInterval (one-sample t confidence interval; item 8) computes a confidence interval for an unknown
population mean m when the population standard deviation s is unknown. The computed
confidence interval depends on the user-specified confidence level.
In the example:
L6={1.6, 1.7, 1.8, 1.9}
