Stainless steel can be susceptible to stress corrosion cracking under certain conditions. A materials engineer is interested in determining the proportion of steel allow failures that are due to stress corrosion cracking. In a recent sample of 200 failures, 30 of them were caused by stress corrosion cracking. Find and interpret a 98% confidence interval for the proportion of failures caused by stress corrosion cracking.
