Chapter 13.8, Problem 27SR

i.

To determine

Greatest number of fat grams in each sandwich.

Answer to Problem 27SR

  $36$ is the greatest fat gram in burger.

Explanation of Solution

Given:

Food data in stem and leaf plot.

From the stem and leaf plot, greatest number of fat grams observed is $36$ which is contained in burgers.

Conclusion:

Thus, $36$ is the greatest fat gram in burger.

ii.

To determine

Type of Sandwich that has a lower amount of fat.

Answer to Problem 27SR

  $8$ fat gram observed in the sandwich.

Explanation of Solution

Given:

Food data in stem and leaf plot.

From the stem and leaf plot, lower amount of fat grams observed is $8$ that is very low amount of fat which is contained in sandwich.

Conclusion:

Thus, $8$ fat gram observed in the sandwich.

ii.

To determine

Measure of variation and any outliners for the data given.

Answer to Problem 27SR

There is o outliners in the chicken

Explanation of Solution

Given:

Food data in stem and leaf plot.

Calculations:

For calculating measure so variation in chicken

  $8,13,13,15,15,18,19,20$

Number of observation is $8$ .

Median is the simple of average between the middle two numbers.

Thus median,

  $\begin{array}{l}=\frac{15+15}{2}\\ =\frac{30}{2}\\ =15\end{array}$

For calculating the the first quartile,

First quartile is the middle value of initial part which is $13$ .

For calculating the third quartile,

Third quartile is the middle value of second part which is $19$ .

Now, for calculating the inter quartile range,

Interquartile range,

  $\begin{array}{l}=Q_3-Q_1\\ =19-13\\ =6\end{array}$

Conclusion:

Thus, there is o outliners in the chicken.
