Chi-Square True/False Question Block

1) True or False: In a chi-square test, the "expected" counts are the values we expect if there is no association between the variables.

True

False

2) True or False: A small chi-square test statistic provides evidence against the null hypothesis.

True

False

3) True or False: If a chi-square test is significant (i.e., there is an association between the variables), we should look at the chi-square components as a follow-up analysis.???????

True

False

Use the Chi-Square test to determine whether these data represent a 50/50 sex-ratio. State your null and alternative hypotheses, expected and observed values, degrees of freedom, calculated chi-square value, interpretation of your chi- square test, and your theoretical conclusion, for N=20, Alpha= 0.05 and Critical Chi-Square = 3.84
