Question

no additional details were added for this assignment. select the statement(s) that accurately describe an appropriate hypothesis for the investigation. if 200 mg of lw20 is given to a male subject with kidney disease, then kidney function will increase. if 50 mg of lw20 is given to male or female subjects with kidney disease, then the kidney function will increase. if 450 mg of lw20 is given to female subjects with polycystic fibrosis daily, then kidney function will increase. if 150 mg of lw20 is given to subjects with chronic kidney disease over several weeks, then kidney function will increase to more than 50%. if 300 mg of lw20 is given to male subjects with kidney disease daily, then kidney function will increase over time.

Explanation:

• A good hypothesis is testable, clear, and general (or appropriately scoped). Option B includes both genders (broader sample) and a clear cause - effect. Option E has a daily dosage (clear treatment) and measures change over time, which is testable. Other options have issues: A is too narrow (only male), C mixes diseases (polycystic fibrosis vs kidney disease), D specifies a percentage (hard to generalize/test broadly).

Answer:

B. If 50 mg of LW20 is given to male or female subjects with kidney disease, then the kidney function will increase.
E. If 300 mg of LW20 is given to male subjects with kidney disease daily, then kidney function will increase over time.
