Test for Homogeneity of Proportions- Oct. 2, 2012

Test for Homogeneity of proportions
- it is used to determine whether the proportions for a variable are equal when several samples are selected from different populations

Hypotheses:

H_o: p₁=p₂=p₃

H₁: at least one proportion is different from the others

Possible decisions:

Do not reject H_{o, it can be assumed that the proportions are equal and the differences in them are due to chance.}

Reject H_{o, it can be assumed that the proportions are not equal.}
