zane is having trouble learning to play the violin. his teacher advises him, \practice makes perfect!\ this advice doesnt help because its too vague — it doesnt suggest what kind of practice, how long to practice, and so on. which of the following parts of the scientific method might provide zane with specific direction?

• formulating hypotheses
• reporting findings
• selecting a sample size
• collecting data

a major strength of experimental research is that it allows researchers to

• use statistics to make inferences.
• infer cause and effect.
• work with people rather than animals.
• identify correlations.

Explanation:

1. For the first question: Formulating hypotheses involves defining specific, testable predictions (like what type/amount of practice improves violin skills), which would give Zane clear, targeted direction. The other options do not address creating specific guidance for his practice.
2. For the second question: Experimental research uses controlled variables (manipulating an independent variable while controlling others), which is the only research method that lets researchers definitively infer a cause-and-effect relationship between variables. Other options are not unique or core strengths of experimental research.

Answer:

1. Formulating hypotheses
2. infer cause and effect.
