I've got 2 questions, hope that's okay they're only short ones 1. when mining copper, the amount retreived per m3 is normally C = 460±140 kg (mean ± std. dev.). when mining nickel, the amount retreived per m3 is normally N = 180±30 kg. If amounts of copper and nickel per m3 are positively correlated, witha correlation of Cor(C, N) = 0.4. Calculate mean and std. dev. of total materials (C + N) retreived per m3. 2. a production company manufactures resistors, 5 resistors are thrown away per hour on average. determine probability that atleast 25 resistors would be thrown away in any 4 hour time window.
