Question

find the critical value(s) and rejection region(s) for a right - tailed chi - square test with a sample size n = 18 and level of significance α = 0.05. click the icon to view the chi - square distribution table. find the critical value(s). (round to three decimal places as needed. use a comma to separate answers as needed.)

Explanation:

Step1: Calculate degrees of freedom

Degrees of freedom $df = n - 1 = 18 - 1 = 17$

Step2: Find critical value

Look up $\chi^2$ table for $df=17$, $\alpha=0.05$ (right-tailed) → 27.587

Step3: Determine rejection region

Rejection region is $\chi^2 > 27.587$

Answer:

Critical value: 27.587
Rejection region: $\chi^2 > 27.587$
