    Option D is right

    Step-by-step explanation:

    Given that the average core for a class of 28 students taking a calculus midterm exam was 72%

    Parameters are numbers that summarize data for an entire population. Statistics are numbers that summarize data from a sample, i. e. some subset of the entire population.

    From the above we see that the measurements pertaining to samples are statistics.

    Thus 72 is a statistic

    Option D is right

    Answer: A. The value is a parameter because the class of 28 students is a population.

    Step-by-step explanation:

    We know that a parameter is a measure calculated from the whole population where as a statistics is a measure calculated from a sample taken from population.

    Given : The average score for a class of 28 students taking a calculus midterm exam was Modifying 72 % with underline.

    Since 72% is the proportion of entire population, thus this value is a parameter.
