QuestionIn a study of 789 randomly selected medical malpractice lawsuits, it was found that 484 of them were dropped or dismissed. Use a 0.05 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. H0:p=0.5\mathrm{H}_{0}: \mathrm{p}=0.5 B. H0:p>0.5H_{0}: p>0.5 H1:p0.5H_{1}: p \neq 0.5 H1:p=0.5H_{1}: p=0.5 C. H0:p0.5H_{0}: p \neq 0.5 D. H0:p<0.5H_{0}: p<0.5 H1:p=0.5H_{1}: p=0.5 H1:p=0.5H_{1}: p=0.5 E. H0:p=0.5H_{0}: p=0.5 F. H0:p=0.5\mathrm{H}_{0}: \mathrm{p}=0.5 H1:p>0.5H_{1}: p>0.5 H1:p<0.5H_{1}: p<0.5
What is the test statistic? z=6.37z=6.37 (Round to two decimal places as needed.) What is the P -value? P -value == \square (Round to three decimal places as needed.)

Studdy Solution
Make a decision based on the P-value and significance level.
Since the P-value is less than the significance level of 0.05, we reject the null hypothesis.
Conclusion: There is sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed.
The P-value is approximately:
0.000 \boxed{0.000}
