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.

Bruce had a disagreement with a new federal agency set up to give additional funds for college to individuals with an aptitude for math. After a hearing, the agency determined that Bruce had no aptitude for math and that he would not receive any funding. Bruce, however, was not discouraged. He told his friend Laura, who just graduated from law school, that he would simply appeal the decision to federal court, have the judge do a fresh review, and provide additional information to the judge regarding his math aptitude that the agency did not have. He feels certain that he will win at the federal court level. Assuming the decision by the administrative agency was a factual finding, what should Laura tell Bruce regarding the standard of review the administrative agency will likely apply?That the agency will likely apply a de novo, or new, review.That the agency will likely apply an arbitrary and capricious standard in any review.That the agency will likely apply a substantial evidence…

Suppose that a healthy person has 10% chance of getting sick that would require $40,000 of medical expenses. Suppose that unhealthy person has a 60% chance of getting sick that would require $100,000 in medical expenses. A) What would be an actuarially fair premium for a healthy person? B) What would be an actuarially fair premium for unhealthy person? C) If everyone has to buy health insurance and 20% of the population are unhealthy and 80% of the population are health, what would be an actuarially fair premium for any person?
Read the following case and provide answers to all the questions. Individuals filing federal income tax returns prior to March 31 received an average refund of $1056. Consider the population of last minute files who mail their tax return during the last five days of the income tax period. A researcher suggest that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. Develop appropriate hypotheses such that rejection of H0 will support the researcher’s contention. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience, a population standard deviation of σ =$1600 may be assumed. What is the p-value? At α=.05, what is your conclusion? Repeat the preceding hypothesis test using the critical value approach. Please use excel formula

A bank is considering offering a loan of $100,000 to a client. If the loan is not offered, then the bank invests the $100,000 receives a sure payoff from the investment of $200 (i.e., receives $100,200 at the end of the year). Prior to a decision of whether or not to offer the loan, the bank can run a credit analysis on the client that returns one of two possible predictions: (1) the client will default on the loan in which case the bank would lose $100,000, (2) the client will pay back the loan with interest in which case the bank receives a payoff of $6,000 (i.e., receives $106,000 at the end of the year). The probability that the credit analysis will return the first prediction (client defaults) is 1%. What is the EVPI?
