Extracted text: The elasticity of a polymer is affected by the concentration of a reactant. Two random samples of size 16 are taken. When low concentration is used, the true mean elasticity is 55 and a standard deviation of elasticity is 4. Meanwhile, when high concentration is used the mean elasticity is 60 and a standard deviation of elasticity is 4. (a) Define the sampling distribution of (XHigh– XLow) (b) Find the probability that (XHigh– XLow) 2 2. Choose the correct answer from drag-drop options. ANSWER (a) The sampling distribution is (b) P (XHigh- XLow)> 2 then the answer is
