Late payment of medical claims can add to the cost of health care. An article reported that for one insurance company,85.1% of the claims were paid in full when first submitted. Suppose that the insurance company developed a new payment system in an effort to increase this percentage. A sample of 200 claims processed under this system revealed that 180 of the claims were paid in full when first submitted.

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

(b) Compute the P-value and interpret its meaning.
