   Given are the following sample outcomes: 28, 23, 17, 30, 28, 21. A one-sample T-test to test H₀:μ = 20 with α = 5% two-sided risk, gives as the value of the test size and corresponding conclusion:

   
   
   1. FALSE: T = 0.90, do not reject H0
   2. FALSE: T = 2.01, do not reject H0
   3. FALSE: T = 2.20, reject H0
   4. TRUE: T = 2.20, do not reject H0
   
   
   1. T = 0.90, do not reject H0: Incorrect
   2. T = 2.01, do not reject H0: Incorrect
   3. T = 2.20, reject H0: Incorrect
   4. T = 2.20, do not reject H0: Correct
