You can purchase a certain type of resistor from supplier X, Y or Z. The probability of having a faulty resistor if the resistor was bought from supplier X is 0.02; from supplier Y is 0.05; and from supplier Z is 0.1. Your company purchased a total of 1000 resistors: 300 from supplier X, 500 from supplier Y, and 200 from supplier Z. Use this information to answer the following questions. 1.What is the probability that a randomly selected resistor...

Answer ASAP: Probability and Statistics question The desired percentage of SiO2 in a certain type of aluminous cement is 5.50 or higher. Suppose that the percentage of SiO2 in a specimen is normally distributed with unknown mean LaTeX: \muμμ but known standard deviation LaTeX: \sigma=0.30σ = 0.30. To test whether the true average percentage is actually less than 5.50 for a particular production facility, we consider LaTeX: H_0: \mu=5.50 \qquad \textrm{vs} \quad H_1: \mu<5.50H 0 : μ = 5.50 vs...
