   Question

   We draw a sample from a normally distributed population N(μ, σ^²), with outcomes: 20, 20, 36 and 20. We test H₀: μ = 20 against H₁: μ ≠ 20 with 5% risk. It is given that σ = 8. How should the conclusion?

   
   
   1. FALSE: The test result is significant, reject H0
   2. FALSE: The test result is significant, do not reject H0
   3. FALSE: The test result is not significant, reject H0
   4. TRUE: The test result is not significant, do not reject H0
   
   
   1. The test result is significant, reject H0: Incorrect
   2. The test result is significant, do not reject H0: Incorrect
   3. The test result is not significant, reject H0: Incorrect
   4. The test result is not significant, reject H0: Correct
