In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 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.

Claim is true that most medical malpractice lawsuits are dropped or dismissed.

Step-by-step explanation:

Given :In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed.

To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Solution:

n =  799

x = 499

We will use one sample proportion test  

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.

Probability of dropped or dismissed is 1/2

Formula of test statistic =

                                        =

                                       = 7.038

p value (z>7.038) is 0

α =0.05

So, p value < α

So, we reject the null hypothesis

So,claim is true

Hence most medical malpractice lawsuits are dropped or dismissed.

Alana needs to carve out a specific monthly budget for herself and keep to it. She could make use of the envelope method to do so. She has to work enough to earn at least $600 in one month, that would take care of her expenses (rent, food, transport etc) that come out to be $524.
