Statistics homework help?! Type 1 and 2 errors?

Question

You read that a statiscal test at significance level alpha=0.05 has power 0.78. What are the probabilities of Type I and Type II errors for this test?

Thanks in advance!

Answer 1

Type 1 error is the alpha level so here it's 0.05

Type 2 error probability for this test is 0.22, because:



Power = 1 - Beta (where Beta is the probability of making a type 2 error)

Your power was 0.78.

1 - 0.78 = 0.22
