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.

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...
