D)alpha level

Question

Quizplus · Accepted Answer

The probability value known as the alpha level is used to determine if the results of a study are due to chance or if they are statistically significant. It is typically set at 0.05 or 0.01, and if the calculated probability is equal to or less than the alpha level, then the null hypothesis is rejected in favor of the alternative hypothesis.
