Given this argument, we can conclude that type I and type II errors are, at any point in time, mutually exclusive events.
In hypothesis testing, the probability of type I and type II errors can be simultaneously reduced by increasing the sample size.
Next, we must find the probability of type I and type II errors in each parallel subsystem.
In Table 1 (Set A), I analyze the various R&QA structures first under the assumption that each component has a 15% chance of making type I and type II errors.
Table 2 (Set C) contrasts the organizational reliability of each system, assuming once again, that each component commits type I and type II errors with a probability of .
