Degree of freedom.: Find the critical value(s) and rejection region(s) for aright-tailed chi-square test with a sample size n=15 and level of significance =0.10.
A. Identify the degrees of freedom.
B. Identify the significance level.
C. find the critical value for the chi-square distribution for a right-tailed test, use the value in a chi-square distribution table that corresponds to d.f. and .
D. find the critical value for the chi-square distribution for a left-tailed test, use the value in a chi-square distribution table that corresponds to d.f. and 1.
E. find the critical values for the chi-square distribution for a two-tailed test, use the values from a chi-square distribution table that correspond to d.f. and 12, and d.f. and 112.
[4/7, 08:49] Kiprutoh: 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
