The blank in the statement "The ____________ distribution is used to develop confidence interval estimates of variances or standard deviations" should be filled with "Chi-square."

So, the complete statement reads: "The Chi-square distribution is used to develop confidence interval estimates of variances or standard deviations."

Would you like more details or have any questions about this topic?

Here are some related questions to expand your understanding:
1. How is the Chi-square distribution used in hypothesis testing?
2. What are the properties of the Chi-square distribution?
3. How do you calculate confidence intervals for variances using the Chi-square distribution?
4. Can the Chi-square distribution be used for non-parametric tests? If so, how?
5. What are the differences between the Chi-square distribution and the normal distribution?

**Tip:** The degrees of freedom in a Chi-square distribution are crucial; they depend on the sample size and are used to determine the shape of the distribution.
