The breaking strength of a fiber used in manufacturing composite material is normally distributed with a...
The breaking strength of a fiber used in manufacturing composite material is normally distributed with a mean of 100 psi. The minimum acceptable breaking strength is 95 psi. If the standard deviation (σ) of the breaking strength is 5.0 psi, then the probability that this fiber will be acceptable = To guarantee that 95% of the fiber produced is acceptable, the standard deviation of the breaking strength should be reduced to σ =

The strength X of a certain material is such that its distribution is found by X = eY, where Y is N(10, 1).  Find the cdf and pdf of X, and compute P(10, 000 < X < 20, 000). Note: F(x) = P(X ≤ x) = P(eY ≤ x) = P(Y ≤ ln x) so that the random variable X is said to have a lognormal distribution.
