- In a randon samole of 60 sections of pipe in a chemical plant, 15 shows signs of serious corrusion. Construct a 95% confidence intervals for the true proportioned pipe sections
Homework Answers
Sample proportion = 15/60 = 0.25
For 95% confidence, z = 1.96
Hence,
95% confidence interval for the true proportioned pipe sections will be:
(0.14, 0.36)

A chemical plant uses process steam that is supplied from a remote boiler house. The steam pipe is uninsulated and has an exposed length of 250 meters. It is currently estimated that the energy losses amount to $3750 annually. It is estimated that the application of 25 mm of insulation will reduce energy losses by 25%, cost of the installation is $25 per meter. If 50 mm insulation is applied, the cost will be $35 per meter and will result...
