Type of pill Placebo Drug A - old Drug B - old Drug C - new Drug D - new 184, 179, 158, 161, 163, 153, 144, 159, 171, 115, 118, 132, 133, 142, 134, 174, 150 166, 173 169, 168 127, 135 155, 1422. Using the data provided in #1, conduct the following contrasts in SPSS. The researcher was interested in examining whether there was a significant difference between (a) the placebo vs. the drug conditions (include all drugs here), (b) the old drugs vs. the new drugs, and (c) the new drugs (Drug C vs. Drug D). Use a = .05 for the set of 3 contrasts. (12 points total) a. State the null and alternative hypotheses for each of the contrasts below. Label the hypotheses as appropriate, so that I know which hypotheses go with which contrasts. (For example, write 'contrast 1,' and then provide the hypotheses for the first contrast, etc.) (2 points)b. Provide the weights for each of the contrasts below. (For example, write 'contrast 1' and then provide the weights for that contrast, etc.). Note: Use zeros for groups that are n_ot being included in the specic contrast, where relevant. (3 points) c. What value of alpha should each contrast be conducted at? Report the value of alpha below (show how you obtained this value - i.e., show your work) (2 points)d. Write the results of each of the contrast tests in APA format below. (5 points)
