Automobile Parts: An important manufacturing process produces cylindrical component parts for the automotive industry. It is important that the process produce parts having a mean diameter of 5.0 millimeters. The engineer involved conjectures that the population mean is 5.0 millimeters. An experiment is conducted in which 100 parts produced by the process are selected randomly and the diameter measured on each. It is known that the population standard deviation is σ = 0.1 millimeter. The experiment indicates a sample average diameter of x = 5.027 millimeters. Does this sample information appear to support or refute the engineer's conjecture?
Let m denote margin of error, n sample size and σ standard deviation. m= zα/2(σn) Solve the above equation for n.

In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metallization. The etch rate is an important characteristic in this process. Two different etching solutions have been compared, using two random samples of 9 wafers for each solution. The observed etch rates are as follows: Solution 1. 9.9 10.6 10.3 9.4 9.3 10.0 9.6 10.3 10.2 Solution 2 10.2 10.6 10.5 10.7 10.6 10.2 10.5 9.8 10.6 Can it be concluded at the a = 0.05 level that the solutions are different?
