Question

Use the given information to state the conclusion about the null hypothesis H0. Assume a significance level of 0.01. Original​ claim: The percentage of settled medical malpractice suits is.at least 50% The hypothesis test results in a P-value of 0.012.

Answer 1

Answer: We reject the null hypothesis.

Step-by-step explanation:

Given : Significance level : $\alpha=0.01$

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. $p\geq 0.5$

Thus,

$H_0:p\geq0.5\\\\H_a:p<0.5$

We know that when the calculated p-value is less than the significance level ($\alpha$) then we reject the null hypothesis, if p-value is greater than the significance level ($\alpha$) then we do not reject.

Now , the calculated value 0.012 is less than the 0.01, so we reject the null hypothesis.
