deviation 1.6 ohms. Similarly, let X2,1, X2,2,...,X28 represent the vendor 2 observed resistances, which are assumed to be normally and independently distributed with mean 85 ohms and standard deviation of 1.8 ohms. What is the sampling distribution of X₁ X₂ ? What is the X₂ ? standard error of X₁ - - The sampling distribution of X₁ X₂ is N( MX₁-X₂ = ,0² x X₁-X₂ = ) (Round the second answer to four decimal places.) The standard error of X₁ - X₂ is i (Round your answer to three decimal places.) IT-IL JCI IN
