which statements about testing a hypothesis are accurate?
□ sometimes scientists must wait for new technologies to test a hypothesis.
□ an experiment tests the effect of a control on another factor in a hypothesis.
□ hypotheses may be tested by making experimental observations, building a model, or analyzing data available in nature.
□ investigations must involve performing experiments, because descriptive investigations are unacceptable in science.

Explanation:

1. New technologies can enable testing of hypotheses that were previously untestable, so the first statement is accurate.
2. An experiment tests the effect of an independent variable, not a control on another factor in a hypothesis, so the second statement is incorrect.
3. Making experimental observations, building models, and analyzing natural - occurring data are valid ways to test hypotheses, so the third statement is accurate.
4. Descriptive investigations are also acceptable in science, so the fourth statement is incorrect.

Answer:

• Sometimes scientists must wait for new technologies to test a hypothesis.
• Hypotheses may be tested by making experimental observations, building a model, or analyzing data available in nature.
