Late payment of medical claims can add to the cost of health care. Suppose 76.2% of the claims were paid in full when first submitted for one insurance company. The insurance company developed a new payment system in an effort to increase this percentage. A sample of 260 claims processed under this system revealed that 215 of the claims were paid in full when first submitted. Complete parts a and b below. a. State the appropriate null and alternative hypotheses. Choose the correct answer below. VB. Họ: ps0.762 O A. Ho: p20.762 Ha: p<0.762 HA: p> 0.762 O D. Ho: zs0.762 O C. Họ: p= 0.762 HA p#0.762 Ha z>0.762 b. Based on the sample data, test the null hypothesis using an alpha level equal to 0.01. Discuss the results of the test. Find the z-test statistic. O(Round to two decimal places as needed.) Enter your answer in the answer box and then click Check Answer.
