Final answer:
The exam can be considered reliable as it produced consistent results for the person over two different testing periods.
Step-by-step explanation:
In this case, the exam can be reasonably determined to be c. reliable. A reliable exam consistently produces similar results when taken multiple times. The fact that the scores of 75 and 76 are statistically the same indicates that the exam is reliable and provides a consistent measure of the student's performance. If a person took a test in December and scored 75, then took the same test again in March and scored 76 (statistically the same), then it can be reasonably determined that the exam is reliable. Reliability in assessment refers to the consistency of a measure, where a measure is considered reliable when it produces the same results under the same circumstances. In this case, since the individual's scores were virtually the same across two different test administrations, this suggests that the test has the ability to yield consistent results over time.
