The population parameter of interest in this case is the proportion of graduates with a GPA of 3.00 or below in the honors program. The university is interested in knowing if this proportion is less than 0.20 or not. Therefore, option A is the correct choice. The mean number (option B), number (option C), and standard deviation (option D) are not relevant in this case.
