a) Resistors made by Zelchotrix Electronics have resistances that varyaccording to a normal distribution with a mean of 1000 ohms and astandard deviation of 160 ohms.i.Gerald randomly selects a resistor from a pack of resistors supplied byZelchotrix Electroncs. What is the probability that the resistor will havea resistance of between 920 and 1150 ohms?ii.The resistance of twelve randomly chosen resistors is measured. What isthe probability that between 3 and 11 (inclusive) of the resistors willhave a resistance that is between 920 and 1150 ohms each?What is the probability that the combined resistance of 12 randomlyselected resistors is between 11.5 kilo ohms and 11.8 kilo ohms?iii.

A manufacturer creates and sells an electronic product that uses one resistor. The product will be defective if its resistor has a resistance below 180 ohms. The manufacturer purchases 1,000 resistors from a new supplier. The supplier claims that the average resistance of their resistors is 200 ohms with a standard deviation of 10 ohms. a. The manufacturer decides to randomly sample n = average resistance is really 200 ohms. If the estimated average resistance is below 190, the shipment will be sent back. Assuming that the suppliers specifications are correct, what is the probability that the shipment is sent back? (I.e. calculate P(X < 190).) Be sure to state any additional assumptions that you make, if any, to arrive at your answer. b. If the supplier's specification is true and the shipment of resistors is used by the manufacturer, what is the probability that a created product will be defective? State any assumptions needed to arrive at 4 of the resistors from the batch to check…
