(d) Explain what the 99% confidence interval means:

With 99% confidence, a randomly selected student in the modified section is expected to score between 0.28 points lower and 5.88 points higher than a randomly chosen student in the regular section.

99% of students in the modified section are expected to score between 0.28 points lower and 5.88 points higher than students in the regular section.

With 99% confidence, the mean score for students in the modified section is expected to be between 0.28 points lower and 5.88 points higher than the mean score for students in the regular section.

There is 99% confidence that all students in the modified section will score between 0.28 points lower and 5.88 points higher than students in the regular section.
