#### Solution Preview

To help you understand type I and type II errors lets consider an example regarding airport security. Metal detectors are used at airports to determine if passengers are carrying weapons. We could use the following hypothesis regarding this scenario:

Null hypothesis - A weapon-free passenger passes through the detector without activating the alarm.

Alternative hypothesis - A weapon-carrying passenger passes through the detector and activates the alarm.

Type I Error:

A type I error can be described as a false positive. In statistical terms, this means that a statistical test rejects the null ...

#### Solution Summary

This solution, comprised of over 400 words, outlines Type I and Type II errors in statistics. For both types of errors, two real world examples are provided with detailed explanations.
