QUESTION 5We wish to test the hypothesis of no difference between the means of the two dependent samples. There are 30 cases in the first sample and 30 cases in the second. The number of degrees of freedom for this test will bea. 28b. 59c. 29d. 58QUESTION 6We plan to use the direct-difference method to test Ho: ?1- ?2 = 0 for a sample of 10 matched pairs. Once the D scores are computed, the procedure is identical to that for testing a hypothesis abouta. a single meanb. the difference between two independent meansc. the difference between two dependent meansd. None of the aboveQUESTION 7We plan to use the direct difference method for dependent samples to test Ho: µ1- µ2 = 0. The following are the observations for our three matched pairs:A          B7          45          44          2SSD =a. 6b. 2c. 8d. 14QUESTION 8We plan to use the direct-difference method for dependent samples to test HO: µ1- µ2 =0. The following are the observations for our three pairs:A         B7         45         44         2Dbar =a. 2b. 1c. 4d. 3QUESTION 9We plan to use the direct-difference method for dependent samples to test HO: ?1- ?2 =0. The following are the observations for our three pairs:A           B7           45           44           2?D2 =a. 14b. 9c. 12d. 16QUESTION 10The rule for constructing an interval estimate of ?D isa.
