Question

Quizplus · Accepted Answer

The level of significance α is equal to (1 - confidence coefficient). This value typically ranges from 0.01 to 0.10, and represents the maximum probability of mistakenly rejecting the null hypothesis. It cannot be a negative value, nor can it be any arbitrary positive value. It is also not within the range of -1.96 to 1.96, which is the range of values for the standard normal distribution at the 95% confidence level.
