The question asks for the proper form for a 95% confidence interval summary statement. Let's analyze the choices:

• Option A: "We are 95% confident that, in the sample, the mean SITA score is between 25.7 and 29.8 points."

  • This is incorrect because a confidence interval refers to a population parameter, not a sample statistic.

• Option B: "We are 95% confident that, in the population, the mean SITA score is between 25.7 and 29.8 points."

  • This is correct. Confidence intervals are used to estimate population parameters, and this statement correctly reflects that interpretation.

• Option C: "We are confident that the mean SITA score is between 25.7 and 29.8 points."

  • This omits the 95% confidence level, making it incomplete and incorrect.

• Option D: "We are confident that 95% of the sample scored between 25.7 and 29.8 points."

  • This is incorrect because confidence intervals refer to population means, not to individual scores within the sample.

The correct answer is B.

Here are 5 related questions to deepen your understanding:

1. What is a confidence interval, and how is it interpreted?
2. How do you calculate a 95% confidence interval for the mean?
3. What does "95% confidence" actually mean in statistical terms?
4. What happens to the confidence interval if you increase the confidence level to 99%?
5. How does sample size affect the width of a confidence interval?

Tip: A larger sample size will result in a narrower confidence interval, giving a more precise estimate of the population parameter.
