Extracted text: In a random sample of 500 handwritten zip code digits, 467 were read correctly by an optical character recognition (OCR) system operated by the U.S. Postal Service (USPS). USPS would like to know whether the rate is at least 90% correct. Construct a 90% confidence interval for the proportion of handwritten zip codes that were read correctly. Round your answers to three decimal places (e.g. 98.765). eTextbook and Media Does this confidence interval support the claim that at least 90% of the zip codes can be correctly read? Yes. O No.
