Extracted text: A procurement specialist has purchased 27 resistors from vendor 1 and 29 resistors from vendor 2. Let X1,1, X1,2,..,X27 represent the vendor 1 observed resistances, which are assumed to be normally and independently distributed with mean 90 ohms and standard deviation 1.3 ohms. Similarly, let X21, X22,...,X29 represent the vendor 2 observed resistances, which are assumed to be normally and independently distributed with mean 97 ohms and standard deviation of 1.9 ohms. What is the sampling distribution of X - X2? What is the standard error of X - X 2? The sampling distribution of X1 – X2 is N(ux-x, i (Round the second answer to four decimal places.) The standard error of X1- X2 is i (Round your answer to three decimal places.) Statistical Tables and Charts
