Addition Rule - correct answer P(A ∪ B) = P(A) + P(A) - P(A ∩ B) aids in computing the chances of one of several events occurring at a given time. Alpha (α) - correct answer The probability of a Type I error. See significance level. Alternative Hypothesis - correct answer The hypothesis stating what the researcher is seeking evidence of. A statement of inequality. It can be written looking for the difference or change in one direction from the null hypothesis or both. ...
