Question

g Suppose that three hypothesis tests are carried out, each using significance level 0.05. What is the worst-case probability of a type I error in at least one of these tests?

Answer 1

The worst-case probability is 0.05

Explanation:

The given significance level (
`\alpha`) = 0.05

since Probability of a type I error is
`\alpha`

∴ P (type I error) = 0.05

0.05 will be the worst-case probability of a type I error in at least one of the tests.
