Question

In which of the following tests is the variable of interest the difference between the values of the observations from the two samples, rather than the actual observations themselves?

A test of hypothesis about the mean of a population of paired differences selected from two related samples.

A test of hypothesis about the difference between the means of two normally distributed populations using independent samples.

A test of hypothesis about the difference between two population proportions, using large independent random samples.

A test of hypothesis about the difference between the variances of two normally distributed populations using independent samples.

Explanation / Answer

In which of the following tests is the variable of interest the difference between the values of the observations from the two samples, rather than the actual observations themselves?

A test of hypothesis about the mean of a population of paired differences selected from two related samples.

A test of hypothesis about the difference between the means of two normally distributed populations using independent samples.

A test of hypothesis about the difference between two population proportions, using large independent random samples.

A test of hypothesis about the difference between the variances of two normally distributed populations using independent samples.

Note: Usually difference between the values of the paired observations are used for paired sample data.
