Answer:
(D) 20
Step-by-step explanation:
We are given the data as the scores, these are:
83, 77, 88, 93, 97, 79, 94, 80, 97, 81
In order to find the range, firstly arrange the data in ascending order, we have
77, 79, 80, 81, 83, 88, 93, 94, 97, 97
Now, the range of the given data is equals to highest data point- lowest data point, thus
[tex]R=97-77[/tex]
[tex]R=20[/tex]
Therefore, the range of the given data set is 20.
Hence, option (D) is correct.
