A nurse researcher reports a 95% confidence interval (CI) of 58.34 and 60.50. How would a nurse reading this research report interpret these results?
1. The two most commonly occurring answers are 58 and 61.
2. Ninety-five out of 100 participants would score either 58.34 or 60.50 on an exam.
3. The researcher can be 95% confident that if the study were repeated with another sample of the same size, the average or mean score would fall between 58.34 and 60.50 in the sample.
4. The researcher can be 5% confident that if the study were repeated with another sample of the same size, the average or mean score would fall between 58.34 and 60.50 in the sample.

Rationale 1: Confidence intervals do not correlate with the most commonly occurring answer.
Rationale 2: Confidence levels are not associated with specific scores on an exam or survey.
Rationale 3: The confidence interval is a range of values (in this case 58.34 and 60.50) that, with a specified degree of probability (in this case 95%), is thought to contain the population value.
Rationale 4: The confidence level is not 5%.
