1. A researcher has been asked to assess the degree of physical complaints among men and women in a manufacturing plant. The researcher believes that women will likely have more physical complaints because the equipment was created primarily for men (as men make up the majority of manufacturing employees) . QUESTION1 . sav contains the data for this study-the variable GENDER codes women as 1, men as O. PHYS_COMPLAINTS provides the average number of physical complaints the participant files over a month. Complete the necessary analyses and report whether the researcher's hypothesis was supported. (20 points)
2. The SPSS file QUESTION2.sav contains data from N=838 nonagenarians on several psychological variables . One, DEPRESS, is a diagnosis of depression, coded as O=not depressed, l=possibly depressed, and 2=depressed. The second variable, DISAB , is an average count of the number of 5 basic activities (e . g. bathing, dressing, driving) an individual cannot complete without a ss istance from another. Scores range from 0 to 5; it is a standard measure of physical disability used by gerontologists.
   The researcher is interested in determining whether depression is related to physical disability in this sample. Complete all analyses you believe to be relevant to this issue (20 point s ).
3. A researcher is interested in learning whether people who test high e r on scales of Traditionalism are more likely to report depression. He plans to coll e ct n e w data on this, but he does have som e data on this that was collected previously (QUESTION2.sav data) to help him guess what effect size he might be loo k ing for in this upcoming study. He wants to have the standard power o f at least .80 for his study.
   Using the Traditionalism scale (TR) in the QUESTION2.s a v dataset, determine how many participants would be ne e ded to find a significant difference betwe e n those who do not hav e depression, and those who clearly do (you should ex c lude those diagnosed with possible d e p r ession).

4. The dataset ADOPT.sav contains data involving children who were adopted at later stages in life.

The data is a s follow s :

1. A r e searcher hyp o th e sizes that a child's attachment to his/her new parent s will increas e over time . Is there evidence to support this hypothesis? (10 points)
2. This researcher also hypothesizes a similar increase in happiness over time as well. Is there support for this hypothesis? (10 points)
3. Traditionally, the state this s a mple is from attempts to match adopted children with parents who are racially similar to the child . ' However, this practice has been in existence prior to the Civil Rights Movement and there is little data currently to support this practice . According to this dataset, does matching children on racial characteristics appear to affect their attachment to their parents? Given this evidence, would you recommend continuing this practice? (10 points)
4. A developmental psychologist suggests that most children begin to become particularly independent of their parents after the age of 13, and suggests that those who are placed at age 12 and under should be compared to those who are placed at age 13 or older. She expects that these two groups will demonstrate different levels of happiness, and that only the under-12 group will become happier over time, whereas the 13+ group will maintain a steady level of happiness. Does this data support the developmental psychologists' expectations? (10 points)
