A statistic.

All are correct .

Refers to the number of data points that can vary given the results of the sample statistics.

The number of values in the final calculation of a statistic that are free to vary.

Abbreviated df.

the calculated likelihood of all events are equally likely.

the outcome of a specific trial in relation to other trials preformed.

the data collected from trials.

the calculated likelihood of any outcome of a trial.

a branch of mathematics where If events are random then the results of a series of independent events are equally likely.

a branch of mathematics concerned with the likelihood of various outcomes for an event.

With a set of independent trials, the outcome of any one trial has no influence on the outcome of any other trial.

With a set of dependent trials, the outcome of any trial has an influence on the outcome of any other trial.

With a set of dependent trials , the outcome of any one trial has no influence on the outcome of any other trial.

With a set of independent trials, the outcome of any one trial has an effect on the outcome of any other trial

p=13/30

none are correct

p=.433

p=15/30

pa=13/30 =.433

pb=.30

p=9/30=30%

p=30%

pb= 9/30 = .30

p=9/30

pc=.27

p=8/30=.27

p=27%

pc=8/30=.267

True

False

False

True

All of the above

Eliminates sample error

Standard Deviation of X̄'s = Standard Error σ/√n

Mean of all sample X̄'s = σ

Shape of distribution becomes normal if n≥ 25

increase the sample size of each sample.

increase the number of samples that you take.

increase the sample size of each sample and increase the number of samples that you take.
