assuming that the difference between two simple means does not change which set of simple characteristics is more likely to produce a significant value for the independent samples t-test a. n1=n2=25 and a small sample variance b. n1=n2=25 and a large sample variance c. n1=n2=100 and a small sample variance d. n1=n2=100 and a large sample variance

Step 1
The formula for the t-test is t = (mean1 - mean2) / sqrt((s1^2/n1) + (s2^2/n2)), where mean1 and mean2 are the sample means, s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes. Show more…
