Statistics Hypothesis Testing Help please!!! The question is:
Testing for Alzheimer's Disease can be a long and expensive process, consisting of lengthy tests and medical diagnosis. Recently a group of researchers devised a 7-minute test to serve as a quick screen for the disease for use in the general population of senior citizens. A patient who tested positive would then go through the more expensive battery of tests and medical diagnosis. The authors reported a false positive rate of 4% and a false negative rate of 8%. What are the null and alternative hypotheses?

Answer 1

I now what the hypotheses are I just don't know how to form them in this instance because I do not know what my p or p-hat is

Answer 2

Since you , are using a test that is being used on citizens. And there are two sides to it. Which are negative and Positive you would have two Types! A type 1 and a type 2. there for saying you sshoukd form your hypothesis something like this. -Which is worse here, a Type I or Type II error? Explain.

Answer 3

I need to form a hypothesis though the Ho: p=? and Ha: p (>,<, not equal to) ? and I don't know how to form that because they do not give me a p that I'm aware of is it the 4% or 8%

Answer 4

But thats just it think two yourself you have two variables here, Type 1 4% and Type 2 8%, there fore you are determining what is causing the reaction. Which your hypothesis is going to be based off both rates, which make up a screen for the disease.

Answer 5

So are there 2 Ho and Ha's ?

Answer 6

Basically, Theres not no one variable in this situation unless you are looking at the disease by itself, which the two Types make up the pro and the con of whether or not there affective
