Question

Which description most accurately summarizes the sample results

Answer 1

The upper left answer.

Explanation:

Using the box diagrams and the given data, the ranges for both the radios can be calculated by subtracting the minimum from the maximum of each data set:

Secure hike Emergency Radio 4.0

Range = 33-21=12

Xtreme Crank Radio

Range = 42 -25

The range of the Xtreme Crank Radio is bigger than the other radio, which means that the data is more spread out, making it less consistent..

The data also shows a lot more entries for the Xtreme Crank Radio that are 30 and above, whereas the secure radio has only a few.

Therefore, the top left answer describes the data best.

Answer 2

To get the statement that closely describes the sample results we proceed as follows:
X-trimeline
lowest value=21
lower quartile=25
median=26
upper quartile=30
highest value=33
range=33-21=12
Radio 4
lowest value=25
lower quartile=27
median=30
upper quartile=36
highest value=42
Range=42-25=17

From the above we conclude that the Answer is: Option A
