Question

1. For a chi square test with 3 degrees of freedom, what is the chi-square critical value if = 0.001? Do not round.

2. Which of the following statements could be a research hypothesis for a chi-square test?

d.) Gender and preferred films are statistically dependent.

3. A researcher conducting a chi-square test from a cross-tabulation with 3 rows and 3 columns obtained a chi-square statistic of 9.51. With these data, what decision should the researcher make, if the researcher is testing the hypothesis at an =0.05 level?

c.) Do not reject the null hypothesis.

4. If a cross-tabulation table had 4 columns and 10 rows, how many degrees of freedom would a chi-square statistic using these data have?

Explanation / Answer

As per the Chegg policy we are advised to do only one question at a time so I am attempting the fourth one.

4. Degrees of freedom = (r - 1)*(c - 1) = (10 - 1)*(4 - 1) = 9*3 = 27

[The answer for 2nd is Option D: Gender and preferred films are statistically dependent]
