   Question

   Two independent samples were drawn and the following was calculated from them:_____. Sample 1: n = 7, mean = 34, variance = 36. Sample 2: n = 5, mean = 25, variance = 46. The T test for testing H₀: μ₁ = μ₂ has a value of 2.430 here. Which critical value and conclusion regarding TRUE are correct here (α = 10% two-sided)?

   
   
   1. FALSE: Critical value is 1.7823, do not reject H0.
   2. TRUE: Critical value is 1.8210, do not reject H0.
   3. FALSE: Critical value is 2.2281, do not reject H0.
   4. FALSE: Critical value is 2.2281, reject H0.
   
   
   1. Critical value is 1.7823, do not reject H0…: Incorrect
   2. Critical value is 1.8210, do not reject H0…: Correct
   3. Critical value is 2.2281, do not reject H0…: Incorrect
   4. Critical value is 2.2281, reject H0…: Incorrect
