Question 1

When we are questioning a rare occurrence or claim and determine the outcome is reasonable we:
A) disregard the lucky alternative and think something is wrong.
B) question the claim.
C) do not doubt the original claim.
D) test again.

Accepted Answer

If we determine that the outcome is reasonable, it means that the claim is most likely true and not just a lucky occurrence. Therefore, we should not doubt the original claim and accept it as true.

Question 2

The _____ in this text is/are a prescriptive technique and visual aid for problem solving.
A) Solution Trail
B) four statistical inference steps
C) vision or strategy
D) technology

Accepted Answer

The Solution Trail is described as a prescriptive technique and visual aid for problem solving in the text. The other options - the four statistical inference steps, vision or strategy, and technology - are not specifically described as prescriptive techniques or visual aids for problem solving in the text.

Question 3

A crucial prevailing theme in this text is:
A) knowing and understanding underlying formulas.
B) correctly translating words into statistics.
C) computation.
D) statistical inference and decision making.

Accepted Answer

The text emphasizes the importance of statistical inference and decision making in various examples and scenarios, such as analyzing data to determine the effectiveness of a new medication or interpreting survey results to inform business decisions. While the other themes may be important, they are not as consistently and prominently highlighted throughout the text.

Question 4

The purpose of _____ is to quantify the normal,everyday deductive process.
A) problem solving
B) experimentation
C) statistics
D) inference

Accepted Answer

Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It quantifies the normal, everyday deductive process by providing a framework for making inferences and drawing conclusions from data. Statistics plays a crucial role in various fields, such as economics, social sciences, and health care, where it helps in decision-making processes based on available data.

Question 5

When we are questioning a rare occurrence or claim and determine the experimental outcome is rare or extraordinary we:
A) disregard the lucky alternative and think something is wrong.
B) do not doubt the original claim
C) decide there is no evidence to suggest the claim is false.
D) test again.

Accepted Answer

When an experimental outcome is rare or extraordinary, it often leads us to suspect that the original claim might be incorrect or that there is an error, rather than attributing it to luck.

Question 6

In a(n)_____ we investigate the effects of certain conditions on individuals or objects in the sample.
A) statistical setting
B) observational study
C) experimental study
D) population

Accepted Answer

An experimental study is the type of study where researchers investigate the effects of certain conditions on individuals or objects in the sample. In an experimental study, the researchers manipulate the independent variable and then measure the effect on the dependent variable. This is in contrast to an observational study where the researcher observes and records information about the sample but does not manipulate any variables. A statistical setting is a general term that refers to the mathematical tools and techniques used to analyze data. A population is the entire group of individuals or objects that the researchers are interested in studying.

Question 7

In the four steps of statistical inference,the claim is BEST described as:
A) the experimental outcome.
B) the likelihood of occurrence of the observed experimental outcome.
C) the status quo-what we assume to be true.
D) our natural reaction to an experimental outcome.

Accepted Answer

The claim refers to the initial assumption or hypothesis that is being tested through the statistical inference process. It represents the status quo or the commonly held belief about the phenomenon being studied, and the goal of the inference process is to determine whether there is sufficient evidence to support or reject this claim.

Question 8

The first step in the process of questioning a rare occurrence is:
A) claim.
B) experiment.
C) likelihood.
D) conclusion.

Accepted Answer

The answer of The first step in the process of...

Question 9

The four technology tools presented in this text are the TI-84 Plus C calculator,Excel 2013,Minitab,and
A) SPSS.
B) CrunchIt.
C) JMP.
D) R.

Accepted Answer

CrunchIt is the fourth technology tool mentioned in the text.
