Chapter 1: Q7E (page 12)

A certain city divides naturally into ten district neighborhoods.How might a real estate appraiser select a sample of single-family homes that could be used as a basis for developing an equation to predict appraised value from characteristics such as age, size, number of bathrooms, distance to the nearest school, and so on? Is the study enumerative or analytic?

Short Answer

Expert verified

Simple random sampling and stratified random sampling can be used as a basis for developing an equation to predict appraised value from different characteristics.

The study is enumerative.

Step by step solution

01

Given information

The district neighbourhoods of a certain city are divided into ten.

02

Describe how a sample of single-family homes could be selected

The sampling procedures that can be used are:

1. Simple Random sampling:Simple random sampling can be used to select the sample of all single-family homes in the city. With this method, biasedness will be eliminated.

2. Stratified Random Sampling:With this method, a simple random sample from each of 10 district neighborhoods can be drawn and from each of the selected homes, the values of the desired variables can be determined.

03

Check whether the study is enumerative or analytic

An enumerative study is a study where the population is finite whereas an analytic study is a study where the population from which a sample is drawn is nonidentifiable.

The provided study is an enumerative study because the population from which the sample needs to be selected is finite and identifiable.

In a famous experiment carried out in 1882, Michelson,and Newcomb obtained 66 observations on the time it took for light to travel between two locations in Washington, D.C. A few of the measurements(coded in a certain manner) were 31, 23, 32, 36, 22, 26, 27, and 31.

a. Why are these measurements not identical?

b. Is this an enumerative study? Why or why not?

The accompanying summary data on CeO2 particlesizes (nm) under certain experimental conditions wasread from a graph in the article 鈥淣anoceria鈥擡nergetics of Surfaces, Interfaces and WaterAdsorption鈥� (J. of the Amer. Ceramic Soc., 2011:3992鈥�3999):

a. What proportion of the observations are less than 5?

b. What proportion of the observations are at least 6?

c. Construct a histogram with relative frequency on the vertical axis and comment on interesting features. In particular, does the distribution of particle sizes appear to be reasonably symmetric or somewhat skewed? (Note:The investigators fit lognormaldistribution to the data; this is discussed in Chapter 4.)

d. Construct a histogram with density on the vertical axis and compare to the histogram in (c).

The article 鈥淪now Cover and Temperature Relationships in North America and Eurasia鈥� (J. Climate and Applied Meteorology, 1983: 460鈥�469) used statistical techniques to relate the amount of snow cover on each continent to average continental temperature. Data presented there included the following ten observations on October snow cover for Eurasia during the years 1970鈥�1979 (in million\({\bf{k}}{{\bf{m}}^{\bf{2}}}\)):

6.5 12.0 14.9 10.0 10.7 7.9 21.9 12.5 14.5 9.2

What would you report as a representative, or typical, value of October snow cover for this period, and what prompted your choice?

Do running times of American movies differ somehow from running times of French movies? The author investigated this question by randomly selecting 25 recent movies of each type, resulting in the following

running times:

Am: 94 90 95 93 128 95 125 91 104 116 162 102 90

110 92 113 116 90 97 103 95 120 109 91 138

Fr: 123 116 90 158 122 119 125 90 96 94 137 102

105 106 95 125 122 103 96 111 81 113 128 93 92

Construct a comparativestem-and-leaf display by listing stems in the middle of your paper and then placing the Am leaves out to the left and the Fr leaves out to the right. Then comment on interesting features of thedisplay.

Exposure to microbial products, especially endotoxin, may have an impact on vulnerability to allergic diseases. The article 鈥淒ust Sampling Methods for Endotoxin鈥擜n Essential, But Underestimated Issue鈥� (Indoor Air,2006: 20鈥�27) considered various issues associated with determining endotoxin concentration. The following data on concentration (EU/mg) in settled dust for one sample of urban homes and another of farm homes was kindly supplied by the authors of the cited article.

U: 6.0 5.0 11.0 33.0 4.0 5.0 80.0 18.0 35.0 17.0 23.0

F: 4.0 14.0 11.0 9.0 9.0 8.0 4.0 20.0 5.0 8.9 21.0

9.2 3.0 2.0 0.3

  1. Determine the sample mean for each sample. How do they compare?
  2. Determine the sample median for each sample. How do they compare? Why is the median for the urban sample so different from the mean for that sample?
  3. Calculate the trimmed mean for each sample by deleting the smallest and largest observation. What are the corresponding trimming percentages? How do the values of these trimmed means compare to the corresponding means and medians?
