A procurement specialist has purchased 26 resistors from vendor 1 and 31 resistors from vendor 2. Let X1,1, X1,2,....X26 represent the vendor 1 observed resistances, which are assumed to be normally and independently distributed with mean 100 ohms and standard deviation 1.4 ohms. Similarly, let X2,1, X22...X31 represent the vendor 2 observed resistances, which are assumed to be normally and independently distributed with mean 104 ohms and standard deviation of 2.0 ohms. What is the sampling distribution of X₁ X₂? What is the standard error of X₁ - X₂? The sampling distribution of X₁ X₂ is N(μX₁-X₂ (Round the second answer to four decimal places.) The standard error of X₁ - X₂ is i = i 0²X₁-X₂ = i (Round your answer to three decimal places.) )
