Gala2k [10]

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75            

H₁ : μ ≠ 3.75

If μ = 3.95 then it means H₀ is not true.                  

then the probability is rejecting the null hypothesis.        

Hence, the probability is the power of the test against the alternative μ=3.95                      

The correct answer is option A
