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.

Dead trees On the west side of Rocky Mountain National Park, many mature pine trees are dying due to infestation by pine beetles. Scientists would like to

use sampling to estimate the proportion of all pine trees in the area that have been infected.

(a) Explain why it wouldn鈥檛 be practical for scientists to obtain an SRS in this setting.

(b) A possible alternative would be to use every pine tree along the park鈥檚 main road as a sample. Why is this sampling method biased?

(c) Suppose that a more complicated random sampling plan is carried out, and that 35% of the pine trees in the sample are infested by the pine beetle. Can

scientists conclude that 35% of all the pine trees on the west side of the park are infested? Why or why not?

Checking for bias Comment on each of the following as a potential sample survey question. Is the question clear? Is it slanted toward the desired response?

(a) Which of the following best represents your opinion on gun control?

1. The government should confiscate our guns.

2. We have the right to keep and bear arms.

(b) A freeze on nuclear weapons should be favored because it would begin a much-needed process to stop everyone in the world from building nuclear

weapons now and reduce the possibility of nuclear war in the future. Do you agree or disagree?

Cocoa and blood flowA study conducted by Norman Hollenberg, professor of medicine at Brigham and Women鈥檚 Hospital and Harvard Medical School,

involved 27healthy people aged 18-72. Each subject consumed a cocoa beverage containing 900milligrams of flavonols (a class of flavonoids) daily

for five days. Using a finger cuff, blood flow was measured on the first and fifth days of the study. After five days, researchers measured what they called 鈥渟ignifi-

cant improvement鈥 in blood flow and the function of the cells that line the blood vessels. What flaw in the design of this experiment makes it impossible to say

whether the cocoa really caused the improved blood flow? Explain.

Is it an SRS? A corporation employs 2000male and 500 female engineers. A stratified random sample of 200 male and 50 female engineers gives each engineer 1 chance in 10 to be chosen. This sample design gives every individual in the population the same chance to be chosen for the sample. Is it an SRS? Explain your answer.

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?
