Solution 34779: Correcting a Domain Error When Calculating a 1-Prop Z-Interval on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.
When trying to calculate a 1-Prop Z-Interval, why do I get a domain error on the TI-83 Plus and TI-84 Plus family of graphing calculators?
When calculating a 1-Prop Z Interval and the number of trials and the
number of successes are given, it is important to input the trials in n
and the number of successes in x. If this done incorrectly, the
calculator will display a domain error.
Please Note: Successes number should not be larger than the number of trials.
Example: The Confidence interval for a population proportion is .95, with 1682 successes out of 2589 trials.
Please see the TI-83 Plus and TI-84 Plus Family guidebooks for additional information.
