SINGLE & TWO SAMPLE TEST

The _________ (or one-sample) binomial test is used to compare a proportion of responses or values in a sample of data to a (hypothesized) proportion in the population from which our sample data are drawn

• double proportion

• single proportion

• exact test

• z-tests

The ______ is the probability of observing values of the test statistic that are as contradictory or even more contradictory to H0 as the test statistic obtained in our sample.

• P-value

• X-value

• A-value

• H0-value

The words "is the same or different from" tell you this is a ______.

• tailed test

• single-tailed test

• two-tailed test

• normal test

________ variable: P’ = the percent of first-time brides who are younger than their grooms.

• Random

• Single

• Normal

• Double

________ for the test: The problem contains no mention of an average.  The information is given in terms of percentages.

• Random

• Single

• P-Value

• Distribution

________ : The test statistic is r, the number of successes in n trials.

• Hypothesis Test

• Q-Test

• Exact Test

• SIngle Proportion

_______ : Several z statistics have been proposed that use the central limit theorem.

• Q-Test

• B-Test

• A-Test

• Z-Test

Single population mean, known population variance (or standard deviation):______.

• Normal test

• Double test

• Test Statistics

• P-Value

Single population mean, unknown population variance (or standard deviation): ______.

• Normal test

• Student t-test

• Exact Test

• Single Proportion

The ______ is to conclude that the proportion of first-time brides that are younger than their grooms is different from 50% when, in fact, the proportion is actually 50%.
