Short Answer

Expert verified

(a)

(b)

(c) Second diagram corresponds to the frequency distribution of the given data.

Step by step solution

01

Part(a) Step 1: Given Information 

The given data is :

we have to construct the stem-and-leaf diagram ,Use one line per stem.

02

Part(a) Step 2: Explanation 

Place the digits of the tens to the left of the vertical line in a stem-and-leaf design, and the digits of the ones to the right of the vertical line.

03

Part(b) Step 1: Given Information 

The given data is:

we have to construct the stem-and-leaf diagram ,Use two lines per stem.

04

Part(b) Step 2: Explanation 

Place the tens digits to the left of the vertical line in a stem-and-leaf diagram, and the ones digits to the right of the vertical line in a stem-and-leaf diagram.

05

Part(c) Step 1: Given Information 

The given data is;

we have to find which diagram corresponds to the frequency distribution of the given data.

06

Part(c) Step 2: Explanation 

Frequency refers to the number of data values that fall into a given category.

The second image has more stems than the first, and it corresponds to the data's frequency distribution.

As a result, the supplied data's frequency distribution matches the second diagram.

The Court's Burrow. The subterranean color (Spalacopus cyan) is a social rodent that lives in large colonies in underground burrows that can reach lengths of up to 600 meters. Zoologists S. Begall and M. Gallardo studied the characteristics of the burrow systems of the subterranean color in central Chile and published their findings in the Journal of Zoology, Landen (Vol. 251, pp. 53-60). A sample of 51 burrows, whose depths were measured in centimeters, yielded the following frequency histogram.

Drug dealer motivation is traditionally attributed to greed or social pressures. Researchers R. Highland and D. Dabney explore possible personality characteristics as a motivation in the article "Using Adlerian Theory to Shed Light on Drug Dealer Motivations" (Applied Psychology in Criminal Justice, Vol. 5, Issue 2, pp. 109-138). The following table lists the types of drug sold from a sample of convicted drug dealers.

Ratings are the percentage of TV homes in the United States tuned into television. Identify the type of data provided by the information in each column of the table

.

Identify an important reason for grouping data.

Some users of statistics prefer pie charts to bar charts because people are accustomed to having the horizontal axis of a graph show order. For example, someone "Republican" is less than "Other" because "Republican" is shown to the left of "Other" on the horizontal axis. Pie charts do not lead to such inferences. Give other advantages and disadvantages of each method.
