1. If an experiment is conducted with 5 conditions and 6 subjects in each condition, what are dfn and dfe? We have 5 conditions (K) and 6 subjects which makes N = 5 * 6 = 30 Degrees of freedom (dfn) = N -1 30 - 1 = 29. Error degrees of freedom (dfe) = N -K 30-5 = 25. 2. Participants threw darts at a target. In one condition, they used their preferred hand; in the other condition, they used their other hand. All subjects performed in both conditions (the order of conditions was counterbalanced). Their scores are shown below. Preferred Non Preferred 12 7 7 9 11 8 13 10 10 9 a. Which kind of t-test should be used? b. Calculate the two-tailed t and p values using this t test. c. Calculate the one-tailed t and p values using this t test. 3. Is the variance for the amount of money, in dollars, that shoppers spend on Saturdays at the mall the same as the variance for the amount of money that shoppers spend on Sundays at the mall? Suppose that the Table shows the results of a study. Saturday Sunday Saturday Sunday 75 44 62 137 18 58 0 82 150 61 124 39 94 19 50 127 62 99 31 141 73 60 118 73 89
