Chapter 1: Q R1.10. (page 78)

Mercury in tuna Is there a difference in the mercury of light tuna and albacore tuna? Use the side by side boxplots and the computer output to write a few sentences comparing the two distributions.

Short Answer

Expert verified

The light mercury is haying more spread than the albacore mercury as light mercury is having spread up to 1.6 while albacore mercury is having spread up to 0.8 only Hence, light mercury is twice spread as much as albacore mercury.

Step by step solution

Given information

Type	N	Mean	St Dev	Min
Albacore	20	0.401	0.152	0.170
Light	144	0.269	1.312	0.012
Type	Q1	Med	Q2	Max
Albacore	0.293	0.400	0.460	0.730
Light	0.059	0.160	0.347	1.500

Concept

A statistical graph or chart is a visual representation of statistical data in graphical form.

Explanation

The albacore mercury is roughly symmetric, with a line in the box nearly in the center and few outliers on the right side, as seen in the given boxplot of the problem, whereas the light mercury is rightly skewed with many outliers.

However, light mercury has a wider spread than albacore mercury, with a spread of up to $1.6$ whereas albacore mercury only has a spread of $0.8$ As a result, light mercury is spread out twice as much as albacore mercury. As a result, light mercury has a wider spread than albacore mercury, with a spread of up to $1.6$ for light mercury and just $0.8$ for albacore mercury. As a result, light mercury is spread out twice as much as albacore mercury.
