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}
