Answer :

Final answer:

The mean of Miah's test scores is 84, the median is 87, and the mode is 87.

Explanation:

To find the mean, we add up all the scores and divide by the total count:

Mean = (87 + 91 + 66 + 87 + 89) / 5 = 420 / 5 = 84

The mean of Miah's test scores is 84.

To find the median, we arrange the scores in ascending order:

66, 87, 87, 89, 91

Since there is an odd number of values, the median is the middle value, which is 87.

The median of Miah's test scores is 87.

To find the mode, we look for the value that appears most frequently:

66 appears once, 87 appears twice, and 89 appears once.

The mode of Miah's test scores is 87.
