Answer: We reject the null hypothesis.
Explanation:
Given : Significance level :

Let p represents the proportion of the settled medical malpractice suits.
Given claim : The percentage of settled medical malpractice suits is at least 50%.
i.e.

Thus,

We know that when the calculated p-value is less than the significance level (
) then we reject the null hypothesis, if p-value is greater than the significance level (
) then we do not reject.
Now , the calculated value 0.012 is less than the 0.01, so we reject the null hypothesis.
