Final answer:

To find the median score for Ms. Mihal's science class, the scores are listed in order and the average of the two middle scores is taken. The median is 84.

Explanation:

The median score for Ms. Mihal's science class is determined by ordering the scores from least to greatest and then finding the middle number. With an even number of scores, the median would be the average of the two middle scores.

  1. First, list the scores in order: 80, 80, 80, 80, 80, 83, 83, 83, 83, 83, 85, 85, 85, 85, 95, 95, 95, 95.
  2. Next, determine the middle position: As there are 18 scores, the middle would fall between the 9th and 10th scores.
  3. Finally, find the two middle scores (83 and 85) and calculate the average: (83 + 85) / 2 = 84.

The median score for Ms. Mihal's science class is 84, so the correct answer is (b).
