Question
In a study of 791 randomly selected medical malpractice lawsuits, it was found that 508 of them were dropped or dismissed. Use a 0,01 signiticance 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? OA. Ho: p>0.5 H:p 0.5 OB. Ho: P 0.5 H: p 0.5 OE. Ho:p:0.5 H:p 0.5 H1:p#0.5 H:P 0.5 H:P-0.5 What is the test statistic? (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? O A. Reject the null hypothesis because the P-value is greater than the significance level,.a O B. Reject the null hypothesis because the P-value is less than or equal to the significance level, .. O C. Fail to reject the null hypothesis because the P-value is greater than the significance level, . O D. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, au Click to select your answer(s). e here to search Wome PrtSen doExplanation / Answer
The statistical software output for this problem is:
One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.5
HA : p > 0.5
Hypothesis test results:
Hence,
Hypotheses: Option E is correct.
Test statistic = 8.00
P - value = 0.000
Conclusion: Option B is correct.
Final conclusion: Option B is correct.
