QUESTION 6 The elasticity of a polymer is affected by the concentration of a reactant. Two random samples of size 20 are taken. When low concentration is used, the true mean elasticity is 56 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-Low) 22. (a) ANSWER: N(4, 1.6) (b) ANSWER: 0.942947
