estimation
|
|
|
Estimation uses sample statistics to predict the value of a _________.
|
Parameter
|
|
|
Technique that allows us to study samples and then make generalizations about the populations from which they were selected.
|
inferential statistic
|
|
|
is a measurement describing some characteristic of a population

|
|
______is an inferential statistic technique using sample data as the basis for drawing conclusions.
|
Estimation
|
|
|
A sample will give a perfect picture of the whole population. T/F?
|
False
It is only a representation of that population |
|
|
single best “guestimate” of a parameter.
|
Point estimation
|
|
|
a range of values that seeks to capture the value of the parameter.
|
Interval estimation
|
|
|
When an interval estimate is accompanied by a specific level of confidence (or probability) it is called a ___________.
|
confidence interval
|
|
|
the probability that our confidence interval contains the true value of population.
|
A confidence level
|
|
|
Is a z-score that separates outcomes that are likely to occur from those that are unlikely to occur.
|
A critical value
|
|
|
Is the maximum likely (with probability 1-α) difference between the observed proportion and the population proportion p.
