Question

In a study of 792 randomly selected medical malpractice​ lawsuits, it was found that 508 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.

Answer 1

H0:p=0.5

H1:p>0.5

Sample proportion=492/792=0.6276

Test statistic:

z=(0.6276-0.5)/sqrt(0.5*(1-0.5)/784)

z=7.14

p-value=P(z>7.14)=0
