Chapter 4: Q AP1.14. (page 278)

Boxplots of two data sets are shown.

Based on the boxplots, which statement below is true?

(a) The spread of both plots is about the same.

(b) The means of both plots are approximately equal.

(c) Plot 2 contains more data points than Plot1

(d) The medians are approximately equal.

(e) Plot 1 is more symmetric than Plot 2

Short Answer

Expert verified

The correct option is (a) The spread of both plots is about the same.

Step by step solution

01

Given information

Boxplots :

02

Concept

A boxplot is a standardized method of depicting data distributions using a five-number summary ("minimum", first quartile (Q1) median, third quartile (Q3) and "maximum"). It can provide information about your outliers and their values.

03

Explanation

We may conclude that option (a) is correct because the length of both boxplots is about the same, indicating that the difference between maximum and minimum values is roughly the same.

Most popular questions from this chapter

A simple random sample of 1200 adult Americans is selected, and each person is asked the following question: “In light of the huge national deficit, should the government at this time spend additional money to establish a national system of health insurance?” Only 39% of those responding answered “Yes.” This survey

(a) is reasonably accurate since it used a large simple random sample.

(b) needs to be larger since only about 24 people were drawn from each state.

(c) probably understates the percent of people who favor a system of national health insurance.

(d) is very inaccurate but neither understates nor overstates the percent of people who favor a system of national health insurance. Since simple random sampling was used, it is unbiased.

(e) probably overstates the percent of people who favor a system of national health insurance.

Effects of TV advertising Figure 4.3displays the six treatments for a two-factor experiment on TV advertising. Suppose we have 150students who are willing to serve as subjects. Describe how you would randomly assign the subjects to the treatments

(a) using slips of paper.

(b) using Table D.

(c) using technology.

Random digits In using Table D repeatedly to choose random samples, you should not always begin at the same place, such as line 101 Why not?

Systematic random sample Sample surveys often use a systematic random sample to choose a sample of apartments in a large building or housing units in a block at the last stage of a multistage sample. Here is a description of how to choose a systematic random sample. Suppose that we must choose 4 addresses out of 100 Because 100/4=25 we can think of the list as four lists of 25 addresses. Choose 1 of the first 25 addresses at random using Table D. The sample contains this address and the addresses 25,50, and 75 places down the list from it. If the table gives 13, for example, then the systematic random sample consists of the addresses numbered 13,38,63, and 88

(a) Use Table D to choose a systematic random sample of 5 addresses from a list of 200 Enter the table at line 120

(b) Like an SRS, a systematic random sample gives all individuals the same chance to be chosen. Explain why this is true. Then explain carefully why a systematic sample is not an SRS.

Sampling by accountants Accountants often use stratified samples during audits to verify a company’s records of such things as accounts receivable. The

stratification is based on the dollar amount of the item and often includes 100% sampling of the largest items. One company reports 5000 accounts receivable. Of these, 100 are in amounts over \(50,000;500 are in amounts between \)1000and\(50,000; and the remaining 4400are in amounts under \)1000Using these groups as strata, you decide to verify all the largest accounts and to sample 5% of the midsize accounts and 1%of the small accounts. How would you label the two strata from which you will sample? Use Table D, starting at line 115 to select only the first3 accounts from each of these strata.
