A study is conducted to assess the relationship between the use of an over-the-counter pain reliever during pregnancy and the development of cleft palate in offsprin Mothers whose children have cleft palate and age-matched controls with unaffected children are interviewed using a standard questionnaire. The study shows that use of the pain reliever during pregnancy increases the risk of cleft formation, even after adjusting for race, other medications, family history of congenital abnormalities and serum folate level (OR = 1.3, p = 0.03). Which of the following biases is of major concern when interpreting the study results?

(Circle either Valid or Invalid for each.) i. Bed a = new WaterBed(); VALID INVALID ii. Bed b = new Bed(); VALID INVALID iii. WaterBed c = new Bed(); VALID INVALID iv. Bed[] d = new Bed[100]; VALID INVALID b. Are the following statements true or false? (Circle either True or False for each.) You should assume that the Bed interface contains only abstract methods (no default methods). i. The WaterBed class must implement some of the method prototypes listed in the Bed interface. TRUE FALSE ii. The Bed interface must contain prototypes for all methods implemented in the WaterBed class. TRUE FALSE iii. The WaterBed class can only implement the Bed interface. TRUE FALSE iv. The Bed interface can be implemented by other classes in addition to WaterBed. TRUE FALSE

9.4 Given: The single-story wood-frame warehouse in Figure 9.B. Roof sheathing of 3/8-in. 24/0 span- rated STRUCTURAL I sheathing is adequate for vertical \"sheathing\" loads. Strength level seismic lateral forces to roof diaphragm are LONGITUDINAL FORCE TRANDVERSE FORCE 23.33 23.35 23.35 SUB PURLINS URLING HEADER 4030-120 ROOF FRAMING PLAN FIGURE 9.B $w_x = w_y = 320 \text{ lb/ft}$ $w_x = w_y = 570 \text{ lb/ft}$ Find: a. Design the roof diaphragm, considering lateral forces in both directions. Show all criteria in- cluding design shears, load cases, tabulated shears, and nailing requirements. If blocking is re- quired, determine at what points it can be omitted. b. Calculate the maximum chord forces for both lateral forces. Also calculate the chord forces at the ends of all headers in the exterior walls. c. Plot the distribution of the collector force for each of the walls with openings. Compare the collector forces and chord forces to determine the critical loading. IRDER 70
