K In a study of 781 randomly selected medical malpractice lawsuits, it was found that 473 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. O A. Ho: p 0.5 O D. Ho: p # 0.5 H1 : p = 0.5 H1 : p = 0.5 O E. Ho: P = 0.5 OF. Ho: P = 0.5 H1 : p > 0.5 H1: p # 0.5 What is the test statistic? z= (Round to two decimal places as needed.) What is the P-value? P-value = (Round to three decimal places as needed.) What is the conclusion about the null hypothesis? O A. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. B. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. O C. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. O D. Reject the null hypothesis because the P-value is greater than the significance level, a. What is the final conclusion
