There are two hypotheses. One is called the_____and the
other the ______. - ANSWER-null hypothesis
alternative or research hypothesis
The testing procedure begins with the assumption that the
_____ is true. - ANSWER-null hypothesis
The goal of the process is to determine whether there is
enough evidence to infer that the alternative hypothesis
is_____. - ANSWER-true
The simplest method of obtaining data is by
________________.
Experiments
survey
,2|Page
direct observation
self-administered questionnaire - ANSWER-Direct
observation
________________ refers to differences between the
sample and the population that exists only because of the
observations that happened to be selected for the sample.
- ANSWER-Sampling Error
Which is a more serious error because taking a larger
sample won't diminish the size, or the possibility of
occurrence, of this error?
Sampling error
Non-sampling error - ANSWER-Non-sampling error
A _______________________ is an action or process that
leads to one of several possible outcomes. - ANSWER-
Random Experiment
A sample space (the list of possible outcomes for an
experiment) must be:
Exhaustive of all possibilities
, 3|Page
In descending order of likelihood
Comprised of only mutually exclusive possibilities -
ANSWER-Exhaustive of all possibilities
Comprised of only mutually exclusive possibilities
Three Approaches to Assigning Probabilities - ANSWER-
1.The classical approach is used by mathematicians to
help determine probability associated with games of
chance. If an experiment has n possible outcomes, this
method would assign a probability of 1/n to each outcome.
2. The relative frequency approach defines probability as
the long-run relative frequency with which an outcome
occurs.
3. The subjective approach has us define probability as
the degree of belief that we hold in the occurrence of an
event.
The classical approach is used by mathematicians to help
determine probability associated with games of chance. If
an experiment has n possible outcomes, this method
would assign a probability of 1/n to each outcome. -
