To determine

Prepare a box-and-whisker plot for the data.

Answer to Problem 17CR

  

Explanation of Solution

Given information:

Given:

  $\begin{array}{l}Dogweights\left(lb\right):\\ 23,15,88,34,33,49,52,67,42,71,28\end{array}$

Calculation:

Here, we have:

  $\begin{array}{l}Dogweights\left(lb\right):\\ 23,15,88,34,33,49,52,67,42,71,28\end{array}$

Now, we will arrange the data in increasing order:

  $15,23,28,33,34,42,49,52,67,71,88$

Now, we will find the maximum and the minimum:

  $\begin{array}{l}Maximum=88\\ Minimum=15\end{array}$

Now, the median will be the middle term of the given data:

  $Median=42$

Now, we will find the first and the third quartile of the given data:

First quartile will be the median of lower half of the data:

  $FirstQuartile=28$

Third quartile will be the median of upper half of the data:

  $ThirdQuartile=67$

Now, we will prepare a box-and-whisker plot for the given data:

  

Hence, the result is shown in the above whisker plot.
