Find critical value ti 84.

Majority of the time the population standard deviation will not be known, so this is the less likely of the two tests for a single mean to be used. All tests will be performed by hand and also with the assistance of the TI-84 family and TI-nspire graphing calculators. Both the p-value and rejection region decision rules will be used.
