The complete data is:
86 84 79 87 75 84 89 90 88 92
In order to find the range of the data set, we need to arrange the given data set in ascending order.
So, we have,
75 79 80 84 84 86 87 88 90 92
The highest data is 92
The lowest data is 75.
The range is given by,
highest data - lowest data
= 92 - 75
= 17
Therefore, the range of these practice test scores is 17.
