(d) Select the correct conclusion.(i) Ho is not rejected. There Is sullicient evidence to indicate a significant differenceDetween the stimull.(ii) Ho is rejected. There is insufficient evidence to indicate a significant difference between the stimuli (iii) Ho is rejected. There is sufficient evidence to indicate a significant difference between the stimuli (Iv)Ho is not rejected. There is insufficient evidence to indicate a significant difference between the stimuli.

8. (12 points) Suppose that a word-association experiment is conducted using eight people and making a comparison of reaction times within each person; that is, each person is subjected to both stimuli in a random order. The reaction times (in seconds) for the experiment are as follows. Person Stimulus 1 Stimulus 2 A N Do the data present sufficient evidence to indicate a difference in mean reaction times for the two stimuli? Test with a = 0.05. (Use /j - #2 = ud. Round your answers to three decimal places.) (a) Choose the correct null and alternative hypotheses. You do NOT need to justify your answer. (i) Ho : pad 0 (ii) Ho : pd = 0 against Ha : pa # 0 (iii) Ho : pd # 0 against Ha : pd = 0 (iv) Ho : #d = 0 against Ha : Pa 0 (b) Compute the test statistic. (c) Determine the rejection region
