Question: Determine if the following variables are quantitative or qualitative: a. Ethnic origin of a candidate for public office b. Score (0-100) on a placement examination c. Fast-food establishment preferred by a student (McDonald's, Burger King, or Carl's Jr.) d. Mercury concentration in a sample of tuna Answer: a. Ethnic origin of a candidate for public office: Qualitative b. Score (0-100) on a placement examination: Quantitative c. Fast-food establishment preferred by a student (McDonald's, Burger King, or Carl's Jr.): Qualitative d. Mercury concentration in a sample of tuna: Quantitative

Step by step solution

01

Identifying Ethnic origin of a candidate for public office as quantitative or qualitative

Ethnic origin refers to the cultural or racial background of a person and can be categorized into different groups, such as African, Asian, Caucasian, Hispanic, etc. It can't be measured in numerical terms. Therefore, the ethnic origin of a candidate for public office is a qualitative variable.
02

Identifying Score \((0-100)\) on a placement examination as quantitative or qualitative

A placement examination score is a numerical value that indicates a student's performance on a test. It can be measured on a scale of 0 to 100. Since the score is represented in numerical terms, it is a quantitative variable.
03

Identifying Fast-food establishment preferred by a student (McDonald's, Burger King, or Carl's Jr.) as quantitative or qualitative

The preferred fast-food establishment by a student is not numerical, rather it can be categorized into one of the given options: McDonald's, Burger King, or Carl's Jr. So, this variable is qualitative.
04

Identifying Mercury concentration in a sample of tuna as quantitative or qualitative

Mercury concentration in a sample of tuna can be measured numerically, typically in parts per million (ppm) or micrograms per gram (碌g/g). It represents an amount or level of mercury in a sample. Since it is measured in numerical terms, this variable is a quantitative one. Now, we have identified each variable as follows: a. Ethnic origin of a candidate for public office: Qualitative b. Score \((0-100)\) on a placement examination: Quantitative c. Fast-food establishment preferred by a student (McDonald's, Burger King, or Carl's Jr.): Qualitative d. Mercury concentration in a sample of tuna: Quantitative

Education Pays Off! Education pays off, according to a snapshot provided in a report to the city of Riverside by the Riverside County Office of Education. \({ }^{7}\) The average annual incomes for six different levels of education are shown in the table. a. What graphical methods could you use to describe the data? b. Select the method from part a that you think best describes the data. c. How would you summarize the information that you see in the graph regarding educational levels and salarv?

Ages of Pennies We collected 50 pennies and recorded their ages, by calculating AGE = CURRENT YEAR - YEAR ON PENNY. \(\begin{array}{rrrrrrrrrr}5 & 1 & 9 & 1 & 2 & 20 & 0 & 25 & 0 & 17 \\ 1 & 4 & 4 & 3 & 0 & 25 & 3 & 3 & 8 & 28 \\ 5 & 21 & 19 & 9 & 0 & 5 & 0 & 2 & 1 & 0 \\\ 0 & 1 & 19 & 0 & 2 & 0 & 20 & 16 & 22 & 10 \\ 19 & 36 & 23 & 0 & 1 & 17 & 6 & 0 & 5 & 0\end{array}\) a. Before drawing any graphs, try to visualize what the distribution of penny ages will look like. Will it be mound-shaped, symmetric, skewed right, or skewed left? b. Draw a relative frequency histogram to describe the distribution of penny ages. How would you describe the shape of the distribution?

An Archeological Find An article in Archaeometry involved an analysis of 26 samples of Romano-British pottery, found at four different kiln sites in the United Kingdom. \({ }^{16}\) The samples were analyzed to determine their chemical composition, and the percentage of aluminum oxide in each of the 26 samples is shown in the following table. a. Construct a relative frequency histogram to describe the aluminum oxide content in the 26 pottery samples. b. What unusual feature do you see in this graph? Can you think of an explanation for this feature? c. Draw a dotplot for the data, using a letter (L, C, I, or A) to locate the data point on the horizontal scale. Does this help explain the unusual feature in part b?

Past U.S. Presidents A data set consists of the ages at death for each of the 38 past presidents of the United States now deceased. a. Is this set of measurements a population or a sample? b. What is the variable being measured? c. Is the variable in part b quantitative or qualitative?

Election 2008 During the spring of 2006 the news media were already conducting opinion polls that tracked the fortunes of the major candidates hoping to become the president of the United States. One such poll conducted by Financial Dynamics showed the following results: "Thinking ahead to the next presidential election, if the 2008 election were held today and the candidates were Democrat [see below] and Republican [see below], for whom would you vote?" The results were based on a sample taken May \(16-18\), \(2006,\) of 900 registered voters nationwide. a. If the pollsters were planning to use these results to predict the outcome of the 2008 presidential election, describe the population of interest to them. b. Describe the actual population from which the sample was drawn. c. Some pollsters prefer to select a sample of "likely" voters. What is the difference between "registered voters" and "likely voters"? Why is this important? d. Is the sample selected by the pollsters representative of the population described in part a? Explain.
