which of the followings is the hypothesis test to be conducted?

a) Ho: p≠0.5 H1: p=0.5

b) Ho: p=0.5 H1: p> 0.5

c) Ho: p=0.5. H1: p≠0.5

d) Ho:p>0.5 H1: p=0.5

e) Ho: p<0.5. H1: p=0.5

f) Ho: p=0.5 H1: p< 0.5

a) What is the test​ statistic?z=

b)What is the​ P-value?

c) What is the conclusion about the null​ hypothesis?

A. Fail to reject the null hypothesis because the​ P-value is less than or equal to less than or equal to the significance​ level, α.

B. Reject the null hypothesis because the​ P-value is greater than the significance​ level, α.

C. Reject the null hypothesis because the​ P-value is less than or equal than or equal to

the significance​ level, α.

D. Fail to reject the null hypothesis because the​ P-value is greater than the significance​ level, α.

What is the final​ conclusion?

A. There is not sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed.

B.There is not sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed.

C.There is sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed.
