For this problem, my task is simple. I have to be able to "summarize what key concepts are being explained in the example. I have to summarize what the problem is explaining and the bottom-line concepts described in the problem."

Can you help me summarize what this problem is stating and be able to explain it in basic English? Thank you.

Resistors come in two varieties, general purpose (with tolerances of 5% or greater) and precision (with tolerances of +2% or less). The tolerance is the amount by which the true resistance can deviate from the stated resistance. For example, a 6.0-kilohm (k() resistor with a tolerance of +10% can be expected to have a measured resis- tance of 6.0 + (.10)(6.0), that is, from 5.4 kQ2 to 6.6 kQ2. Assuming that a uniform density adequately describes the possible values of x, then the true resistance x of a randomly selected 6.0-ko resistor is a random variable described by the density func- tion (see Chapter 1 for the definition of uniform densities): f ( x ) = 1.2 for 5.4 .16) = P(->.16 ) = P(x
