ZIntl
This one-sample Z confidence interval, shown as
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:
{299.4 297.7 301 298.9 300.2 297}

TIntl
This one-sample t confidence interval, shown as
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:
