3. If you reject H0 in a test of a contingency table, you conclude that based on your data:

a. The two nominal variables are independent

b. The two nominal variables are equal

c. The two nominal variables have the same proportions listed in H0

d. None of these choices

Explanation / Answer

1. The sampling distribution of the test statistic for a goodness-of-fit test with k categories is a ?

it will chi square test

2. For a contingency table with 4 rows and 4 columns, the chi-square test will have degrees of freedom equal to:

df = (4*4) - 1 = 15

3. If you reject H0 in a test of a contingency table, you conclude that based on your data:

Rejection of Ho means that alternative hypothesis is accepted.

That is not given in optioins.

So, option D is correct
