Significance of new system is higher than the article reported the previous system.

Late payment of medical claims can add to the price of healthcare. An article (M. Freudenheim, "The Check Is Not in the Mail," The New York Times, May 25, 2006, pp.C1, C6) reported that for one insurance company, 85.1% of the claims were paid in full while first submitted. Assume that the insurance company developed a new payment system in an effort to enhance this percentage. A sample of 200 claims processed under this new revealed that 180 of the claims were paid in full as first submitted.

At the 0.05 level of implication, is there evidence that the proportion of claims processed under this new system is higher than the article reported for the previous system?
