Question

practice it!
during the fall semester at school, you notice that you do not hear as many crickets chirping as you remember during the summer months.
you decide to investigate and conduct an experiment to find the reason.
you begin with the question, \how does temperature affect how often crickets chirp?\
select the statement(s) that would be an appropriate hypothesis when conducting the investigation above.
□ if the cricket is happy, then it will chirp more often.
□ if it is winter, then all the crickets will die.
□ crickets only chirp in the summer months.
□ if the temperature is cold, then the crickets will chirp less often
□ if the temperature is warm, then the crickets will chirp more often.

• please choose an answer

Explanation:

To determine appropriate hypotheses, we focus on the question about temperature affecting cricket chirping.

• "If the cricket is happy..." is invalid as happiness is not measurable/related to temperature.
• "If it is winter..." is about season (not direct temp - chirp relation) and extreme (all die) not about frequency.
• "Crickets only chirp..." is a statement, not a testable hypothesis format (if - then) and too absolute.
• "If the temperature is cold, then the crickets will chirp less often" relates cold temp (independent variable) to less chirping (dependent variable), testable.
• "If the temperature is warm, then the crickets will chirp more often" relates warm temp to more chirping, testable.

Answer:

D. If the temperature is cold, then the crickets will chirp less often
E. If the temperature is warm, then the crickets will chirp more often
