A) we can be sure that the claim is correct.
B) we can state that the claim is wrong.
C) we cannot make any statement.

Answer 3

statistics

Question 4

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.

Question 5

A researcher makes a claim and then runs an experiment to test the claim.The researcher gets results that are quite unexpected but still within the limits of the claim.The researcher should:

A) disregard luck and think something is wrong with the claim.
B) abandon the claim.
C) not use the results to cast doubt on the original claim.
D) rerun the experiment.

Question 6

The __________________ in this text is (are) a prescriptive technique for problem solving.

A) Socratic method
B) four statistical inference steps
C) vision or strategy
D) technology

Question 7

In a(n) _______________, we investigate the effects of certain conditions on individuals or objects in the sample by consciously varying the situation.

A) statistical setting
B) observational study
C) experimental study
D) population

Question 8

An experiment is invalid (no good) for making inferences if:

A) the claim could not possibly be wrong.
B) the claim could not possibly be right.
C) the claim has an equal likelihood of being wrong or right.
D) All of the above.

Question 9

The first step in the process of questioning a rare occurrence is to:

A) do an experiment.
B) make a claim.
C) state a conclusion.
D) assess the likelihood of the results.

Question 10

A) SPSS.
B) CrunchIt.
C) JMP.
D) MATLAB.

Question 11

A researcher makes a claim and then runs an experiment to test the claim.The researcher gets results that are very unexpected and definitely outside of the limits of the claim.The researcher should:

A) disregard the lucky alternative and think is the original claim may be wrong.
B) not doubt the original claim.
C) decide there is no evidence to suggest the claim is false.
D) test the claim again.
