    six step hypothesis test

    A study of voting preferences among enlisted soldiers (of differing educational levels) in the military reveals the follow patterns (the sample size if 445).

    1 Of 395 high school graduates, 90 describe themselves as Democrats, 170 as Independents, and 135 as Republicans
    2 Of 27 college graduates, 3 describe themselves as Democrats, 18 as Independents, and 6 as Republicans
    3 Of 23 who did not complete high school, 7 describe themselves as Democrats, 7 as Independents, and 9 as Republicans


    Using the six-step hypothesis-testing framework from class, please test for independence between the level of education and political party affiliation. Set the level of significance at .05. (9 points)


    H 0:
    Ha:
    n = , a=





    What is your conclusion? Are the two variables independent?

    I used the chi square test on excel and this is the answer I get. 1.29034E-11 which mean we need to reject the null hypothesis


    is this correct?
