QUESTION:
Thickness measurements of a coating process are made to the nearest hundredth of a millimeter. The thickness measurements are uniformly distributed with values 0.15, 0.16, 0.17, 0.18, and 0.19. Determine the mean and variance of the coating thickness for this process.
ANSWER:
Step 1 of 3
Let us consider a random variable \(X\) that presents thickness measurements of a coating process. And the thickness measurements are Uniformly distributed with values 0.15, 0.16, 0.17, 0.18, and 0.19. We need to determine the mean and variance of \(X\).
