Final answer:
The statement is true as term limits can lead to a statistically significant increase in female representation in state legislatures by creating more opportunities for women to run for and win open seats.
Step-by-step explanation:
The statement that term limits have produced a statistically significant increase in the number of women serving in state legislatures is True. Term limits may disrupt the status quo and open up more opportunities for underrepresented groups, including women, by limiting the time that incumbents can serve. This creates more open seats, which can facilitate a more diverse set of candidates, including women, seeking office. Over time, these changes can contribute to an increase in female representation in state legislatures.
