When two independent random samples of sizes
and
have been selected from populations with means
and
and variances
and
, the standard error of the sampling distribution of
the difference between the two sample means, is found by taking the square root of the sum of the two population variances; namely,
.
Independent Random Samples
Samples selected from a population in such a way that each individual has the same chance of being selected, and the selection of one individual does not affect the selection of another.
Population Means
The average of a set of characteristics (such as age, weight, etc.) of every member of a population.
