Quizplus · Accepted Answer

A p value is a measure of the probability of obtaining a statistic as extreme as or more extreme than the one observed, under the assumption that the null hypothesis is true. A smaller p value indicates that the obtained statistic is more rare or unusual, and therefore provides evidence against the null hypothesis. Choices A and B refer to levels of significance and power in hypothesis testing, respectively, and choice C refers to a standardized value of a sample mean or proportion.
