(b) If the researcher decides to test this hypothesis at the x = 0.05 level of significance, determine the critical value(s). Although technology or a t-distribution table can be used to find the critical value, in this problem use the t-distribution table given. Critical Value: -1.714 (Round to three decimal places. Use a comma to separate answers as needed.) ... (c) Draw a t-distribution that depicts the critical region. Choose the correct answer below. OA. O B. O C. 0 ta - ON -ta/2 0 ta/2 -ta 0
