Suppose that a word-association experiment is conducted using eight people as blocks 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 1 2 3 4 5 6 7 8 Stimulus 1 Stimulus 2 3 4 1 1 2 O Ho: O Ho: = 0 versus H: O Ho: # < 0 versus H₂: ⒸH₂ Hd 0 versus Ha: 1 State the null and alternative hypotheses.. Ho: = 0 versus Hai Hd 0 2 2 4 3 3 2 4 Do the data present sufficient evidence to indicate a difference in mean reaction times for the two stimuli? Test using = 0.05. (Use -- M₂ = Hα) 0 versus H₂ = 0 0 > D 2 +0 4 2 State the test statistic. (Round your answer to three decimal places.) t= State the rejection region. (If the test is one-tailed, enter NONE for the unused region. Round your answers to three decimal places.) t> Suppose that a word-association experiment is conducted using eight people as blocks and making a comparison of reaction times within each person; that is, each person is subjected to both stimuli in a random order.
