I have attached the assignment. I need questions 2 through 5 completed.


Week 2: A ExercisesCrosstabs/Risk/Correlations (1) The following data designate whether or not patients complied with a medication regimen (1 = yes, 0 = no), for an experimental group that participated in a special intervention designed to promote perceived mastery over health events, and a “usual care” control group: Experimental 1 0 0 1 1 1 0 1 0 1 0 1 1 1 0 Control 0 0 1 0 0 0 1 0 1 0 0 1 1 0 0 Construct a contingency table for these data, computing both row and column percentages for each of the four cells. (2) Examine the results in the following table: Type of Infraction Mean n (%) Females n (%) Total N (%) Drug abuse at work 36 (30.3) 117 (23.0) 153 (24.2) Drug abuse off work 15 (12.6) 63 (12.4) 78 (12.4) Violating a prior Board agreement 9 (7.6) 46 (9.1) 55 (8.8) Working with lapsed license 2 (1.7) 36 (7.1) 38 (6.1) Care errors 4 (3.4) 32 (6.3) 36 (5.7) Medication errors 8 (6.7) 26 (5.1) 28 (4.5) Providing care without physician order 2 (1.7) 26 (5.1) 28 (4.5) Documentation errors 8 (6.7) 19 (3.7) 27 (4.3) All other infractions 35 (29.4) 143 (28.1) 178 (28.4) Total 119 (100.0) 508 (100.0) 627 (100.0) a. Are the percentages shown in this table row percentages or column percentages? b. Compute the percentages the opposite way, and then answer this question: Given that males represent 7.5% of all licensed nurses in Missouri, which (if any) infractions in the table were committed by males at a rate lower than their representation among nurses in that state? c. Based on the recomputed percentages in Exercise A2b, for which infraction were male nurses most notably overrepresented? (3) The contingency table below presents fictitious data regarding an intervention to reduce pressure ulcers in nursing home residents. Using these data, compute ARE, ARNE, ARR, RR, RRR, OR, and NNT. Pressure Ulcer No Pressure Ulcer Total Control Group 15 35 50 Experimental Group 5 45 50 Total 20 80 100 (4) Below are the values for diastolic and systolic blood pressure for 10 people: Diastolic 90 80 90 78 76 78 80 70 76 74 Systolic 130 126 140 118 114 112 120 110 114 116 Construct a scatterplot that shows the relationship between the variables. Verbally describe the direction and magnitude of the relationship. (5) Compute the correlation coefficient (Pearson’s r) to summarize the relationship for the blood pressure data presented in question (4). How accurate was your verbal description of the scatterplot, as compared to the value of the coefficient?
