Suppose a researcher obtains a chi-square statistic of 8.7, from analyses from cross-tabulation table with five rows and two columns. Determine whether the relationship between the two variables is statistically significant at the α = .05 level. Group of answer choices: Statistically significant Not statistically significant More information is needed
Added by Maureen F.
Step 1
Given that the cross-tabulation table has 5 rows and 2 columns, the degrees of freedom can be calculated as (number of rows - 1) * (number of columns - 1) = (5-1) * (2-1) = 4. Show more…

For each of the following situations, would a chi-square test based on a $2 \times 2$ table using a level of 0.05 be statistically significant? Justify your answer. a. chi-square statistic $=1.42$ b. chi-square statistic $=14.2$ c. $p$ -value $=0.02$ d. $p$ -value $=0.15$

We have given the value obtained for the test statistic, $z,$ in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the $5 \%$ significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. Left-tailed test: a. $z=-0.74$ b. $z=1.16$
