Which of the following is the hypothesis test to be conducted?
A.
H0: p>0.5
H1: p=0.5
B.
H0: p<0.5
H1: p=0.5
C.
H0: p≠0.5
H1: p=0.5
D.
H0: p=0.5
H1: p>0.5
E.
H0: p=0.5
H1: p<0.5
F.
H0: 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?
- Reject the null hypothesis because the P-value is greater than the significance level, α.
- Reject the null hypothesis because the P-value is less than or equal to the significance level, α.
- Fail to reject the null hypothesis because the P-value is greater than the significance level, α.
- Fail to reject the null hypothesis because the P-value is less than or equal to the significancelevel, α.
What is the final conclusion?
- There is not sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed.
- There is not sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed.
