Assuming a 5-point difference between the two sample means,which set of sample characteristics is most likely to produce a significant value for the independent-measures t statistic?
A)Large sample sizes and small sample variances
B)Large sample sizes and large sample variances
C)Small sample sizes and small sample variances
D)Small sample sizes and large sample variances
