Question

The probability of making a type I error when comparing all means in an experiment is called:

a) Null hypothesis
b) Power of the test
c) Type II error
d) Significance level

Answer 1

The probability of making a type I error when comparing all means in an experiment is called the significance level.

Step-by-step explanation:

The probability of making a type I error when comparing all means in an experiment is called the significance level. This is denoted by the Greek letter a. The significance level represents the maximum allowable probability of incorrectly rejecting the null hypothesis when it is actually true.
