Final answer:
The alpha level does not have to be set at 0.05, it can be set at any value.
Step-by-step explanation:
False. The alpha level does not have to be set at 0.05, it can be set at any value. The alpha level, also known as the level of significance, is the probability of making a Type I error, which is rejecting the null hypothesis when it is true. The common practice is to set the alpha level at 0.05, but it can be adjusted depending on the specific needs of the study. For example, in some studies, a more stringent alpha level of 0.01 may be used to reduce the chance of Type I error.
