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}
