Question

what is the range of the data? 1 8.4 2 8.2 3 8.5 average 8.37 the range is 25.1 cm. the range is 8.37 cm. the range is 0.13 cm.

Explanation:

Step1: Identify max and min values

The data values are 8.4, 8.2, 8.5. The maximum value is 8.5 and the minimum value is 8.2.

Step2: Calculate the range

The formula for the range of a data - set is $Range = Max - Min$. So, $Range=8.5 - 8.2=0.3$. But there seems to be a mistake in the options provided as the correct range value calculated from the given data (8.4, 8.2, 8.5) is 0.3. If we assume the data was entered wrong and we go with the closest option based on the concept of range calculation, we note that the correct way to calculate range is subtracting the smallest from the largest value in the data set.

Answer:

The range is 0.3 (but if we must choose from given options, none is correct as calculated value doesn't match; if we assume some data - entry error and go with the closest concept - related option, we can't accurately choose from the provided ones as they are incorrect in relation to the proper range calculation from the given data values 8.4, 8.2, 8.5).
