decision rule depends of 3 factors ....
[Hint: Steps of hypothesis 1 and 2]

Steps of hypothesis testing (5)
p-value, what is it and what is its significance?
Interpreting p-value
a) Reject Ho if p = or < α
b. Do not reject Ho if p > α
Type 1 Error (α)
Type 2 Error (β)
χ2 Test are based on -----
When do you use χ2 statistical test
a) In χ2 , what does K stands for?
b) how do you calculate the degree of freedom (df)?
c) how do you determine the critical value in χ2?
W/n χ2 , what does the lower- or upper-tailed tests stand for?
in χ2 , the rejection region is ALWAYS on the right upper-tail (Y or N)
α = P(Type 1 Error); assuming α = 0.005, what does that mean?
