A factory produces 1000-ohm (R) resistors that have 15 percent tolerance. Let X denotes the resistance of a resistor. Assuming that X is a Gaussian random variable with mean 1000 and variance 2000. a) Find the probability that a resistor picked at random will be rejected. b) Below what value do we get the smallest-resistance 25% of the resistors?
