c. For α = 0.025, find the critical value of x². Specify the rejection and nonrejection regions on the chi-square distribution curve. Enter the exact answer from the chi-square distribution table. x² = The rejection region is of the critical value of x². The nonrejection region is d. Find the value of the test statistic x². Round your answer to three decimal places. The value of the test statistic x² is i e. Using a = 0.025, would you reject the null hypothesis? V of the critical value of x².
