Answer:
Explanation:
To find the lower and upper quartiles of a set of data, the data must first be sorted in ascending order.
Out of the four options given, the only one in ascending order is "lower quartile: 80.5, upper quartile: 88", so that must be the correct answer.
The lower quartile divides the lower 25% of the data from the upper 75%, and the upper quartile divides the upper 25% of the data from the lower 75%. So in this set of data, 80.5 represents the point below which 25% of the data falls, and 88 represents the point below which 75% of the data falls. The remaining 25% of the data falls between 88 and 93, which is the interquartile range. The value 93 represents the point below which 25% of the data falls.
