hypothesis testing statement

pinkyloop — Wed, 30 Oct 2019 02:04:13 GMT

This is what i am trying to solve;

Medical researchers believe that a patient’s cholesterol level drops after a

heart attack

Develop the hypothesis statements to test this statement and the

associated testing matrix or confusion matrix. The time period of

interest is from Day 2 after the attack to Day 4 after the attack.

Test this claim at the alpha = .05 level.

i honestly don't know how to do the testing.

do i use a proc ttest?

>Develop the hypothesis statements to test this statement

This part is first. What is your hypothesis?

And since this is likely homework, the test is likely one you've covered in class, so which tests have you covered in class so far?

we have covered proc freq and proc ttest

That alternative hypothesis is not equal to zero?

figured it out
If i test the cholesterol level of individuals after a heart attack ,the Cholesterol level drops

Cholesterol level is continuous so you'd use a t-test then.
