In a study of 786 randomly selected medical malpractice lawsuits, it was found that 518 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.
Which of the following is the hypothesis test to be conducted?
A.
Upper H 0 : p equals 0.5H0: p=0.5
Upper H 1 : p greater than 0.5H1: p>0.5
B.
Upper H 0 : p equals 0.5H0: p=0.5
Upper H 1 : p less than 0.5H1: p<0.5
C.
Upper H 0 : p equals 0.5H0: p=0.5
Upper H 1 : p not equals 0.5H1: p≠0.5
D.
Upper H 0 : p not equals 0.5H0: p≠0.5
Upper H 1 : p equals 0.5H1: p=0.5
E.
Upper H 0 : p less than 0.5H0: p<0.5
Upper H 1 : p equals 0.5H1: p=0.5
F.
Upper H 0 : p greater than 0.5H0: p>0.5
Upper H 1 : p equals 0.5H1: p=0.5
