Answer:
0.15 is the probability of a Type II error for this test.
Step-by-step explanation:
We are given the following information in the question:
Alpha, α = 0.05 = 5%
P‑value = 4% = 0.04
Power of test = 85% = 0.85
We have to find the probability of a Type II error for this test.
- The type II error is the error that occurs when we fails to reject a null hypothesis when it is false.
The relation between power of a test and type II error is given as:

Putting values, we get,

0.15 is the probability of a Type II error for this test.
These angles are vertical angles meaning that they are equal to each other. Here is the equation for this problem:
x + 40 = 3x
Combine like terms
(x-x) + 40 = 3x - x
40 = 2x
Isolate x
40/2 = 2x/2
x = 20
