Critical Regions and Hypothesis testing

Question 1

What is a critical region?

Answer 1

The area where H0 is rejected

Question 2

What do you do if x>y?

Answer 2

x>y = 1 - 0.0y

Question 3

How do you answer critical region questions?

Answer 3

Let P be the probability of …
H0: P=
H1: P?
X~B(N,P)
P(X? ) = …
… =< / = / >= … - significant? reject? new P?

Question 4

How do you Hypothesis test with normal distribution?

Answer 4

X~N(u, (o-^2)/n)
let u be …
Ho: … H1: …
rewrite the formula ^
P(x …)
calculate P
< or > than SL

Question 5

How do Hypothesis test for zero correlation?

Answer 5

e = population correlation coefficient
use the data sheet to find the critical values
