b) A procurement specialist purchased 28 resistors at random from Supplier 1 and 32 resistors from Supplier 2. Each resistor's resistance is measured. Assume that the resistance from TM Supplier 1 resistors are normally and independently distributed with mean of 105 ohm and standard deviation of 1.58 ohm, and that the resistance from Supplier 2 resistors are normally and independently distributed with mean of 100 ohm and standard deviation of 1.45 ohm. What is the standard error of the observed difference in the sample mean resistances of resistors purchased from both suppliers? ™M Calculate the probability that the difference in the sample mean resistance is at least 6 ohm.
