The Ohio Department of Agriculture tested 203 fuel samples across the state
in 1999 for accuracy of the reported octane level. For premium grade, 14 out
of 105 samples failed (they didn't meet ASTM specification and the FTC
Octane posting rule). Find a 99% confidence interval for the true population
proportion of premium grade fuel-quality failures. Show Calculation.
