hypothesis testing statement

[pinkyloop]

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?

That alternative hypothesis is not equal to zero?

[pinkyloop]

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

[Reeza]

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

Thanks!

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?

[pinkyloop]

we have covered proc freq and proc ttest
