Being extremely anxious and 100 being totally not anxious, rate your level of anxiety in this U.S.
Economy" results in

Accepted Answer

Question 5

A study is under way in Yosemite National Forest to determine the adult height of American
Pine trees.Specifically, the study is attempting to determine what factors aid a tree in reaching
Heights greater than 60 feet tall.It is estimated that the forest contains 25,000 adult American
Pines.The study involves collecting heights from 250 randomly selected adult American pine
Trees and analyzing the results.Identify the population from which the study was sampled.

Accepted Answer

The population from which the study was sampled is the 25,000 adult American pine trees in the forest.

Question 6

on the U.S.economy.
-Referring to Scenario 1-2, the possible responses to the question "How many more months do
You think the U.S.economy will require to get out of a recession?" are values from a

Accepted Answer

The number of months is a countable quantity, making it a discrete numerical variable.

Question 8

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view
on the U.S.economy.
-Referring to Scenario 1-2, the 2,150 adults make up

Accepted Answer

The 2,150 adults are the sample, as they are a subset of the population (all adults in the U.S.) being studied. The primary data source would be the survey itself, while any other sources used to gather information (such as previous studies or reports) would be considered secondary data sources.

Question 9

Which of the following is most likely a population as opposed to a sample?

Accepted Answer

The registered voters in a county are most likely a population because they represent the entire group of people in that county who are eligible to vote. The other options involve selecting a smaller group from a larger population, which would be a sample.

Question 10

Referring to Scenario 1-2, the possible responses to the question "In which year do you think the
Last recession in the U.S.started?" are values from a

Accepted Answer

The year in which a recession started is a specific, countable value, making it a discrete numerical variable.

Question 11

Referring to Scenario 1-2, the possible responses to the question "How many people in your
Household are unemployed currently?" result in

Accepted Answer

The number of unemployed people in a household is a ratio scale variable because it has a true zero point (zero unemployed people) and allows for meaningful comparisons using multiplication and division.

Question 12

The portion of the universe that has been selected for analysis is called

Accepted Answer

A portion of the universe that is selected for analysis is called a sample. A frame refers to the list of individuals included in the sample, while a primary data source is the original source of data collected for research, and a secondary data source is data obtained from another source.

Question 13

Referring to Scenario 1-2, the possible responses to the question "How many out of every 10 U.S.
Voters do you think feel that the U.S.economy is in a good shape?" result in

Accepted Answer

The response to the question involves a count of voters, which is a quantitative measure with a true zero point, making it a ratio scale variable.

Question 14

Referring to Scenario 1-2, the possible responses to the question "How would you rate the
Condition of the U.S.economy with 1 = excellent, 2 = good, 3 = decent, 4 = poor, 5 = terrible?"
Result in

Accepted Answer

The responses represent an ordinal scale variable because they indicate a ranking or order of the condition of the U.S. economy from excellent to terrible, but the intervals between the responses are not necessarily equal.

Question 15

The universe or "totality of items or things" under consideration is called

Accepted Answer

The term used to refer to the entire universe of items or things under consideration in statistical analysis is "population". A sample in statistics refers to a subset of the population that is selected for analysis. Primary and secondary data sources refer to the origin or nature of the data being used, but are not related to the universe of items being analyzed.

Question 16

Referring to Scenario 1-2, the possible responses to the question "What do you think is the
Current unemployment rate?" result in

Accepted Answer

The unemployment rate is a ratio scale variable because it has a true zero point and the differences between values are meaningful, allowing for the calculation of ratios.
