In a study of 805 randomly selected medical malpracticelawsuits, it was found that 514 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 beconducted?

A.

Upper H 0 : p greater than 0.5 Upper H 1 : p equals 0.5

Upper H 0 : p greater than 0.5

H0:p>0.5

Upper H 1 : p equals 0.5

H1:p=0.5

B.

Upper H 0 : p equals 0.5 Upper H 1 : p greater than 0.5

Upper H 0 : p equals 0.5

H0:p=0.5

Upper H 1 : p greater than 0.5

H1:p>0.5

C.

Upper H 0 : p equals 0.5 Upper H 1 : p less than 0.5

Upper H 0 : p equals 0.5

H0:p=0.5

Upper H 1 : p less than 0.5

H1:p<0.5

D.

Upper H 0 : p equals 0.5 Upper H 1 : p not equals 0.5

Upper H 0 : p equals 0.5

H0:p=0.5

Upper H 1 : p not equals 0.5

H1:p0.5

E.

Upper H 0 : p not equals 0.5 Upper H 1 : p equals 0.5

Upper H 0 : p not equals 0.5

H0:p0.5

Upper H 1 : p equals 0.5

H1:p=0.5
