If n = 15 for each sample,which of the following sets of data provides the clearest difference between the two samples? A)A sample mean difference of 5 points with s² = 5 for both samples B)A sample mean difference of 5 points with s² = 10 for both samples C)A sample mean difference of 10 points with s² = 5 for both samples D)A sample mean difference of 10 points with s² = 10 for both samples

The sample mean difference of 10 points is larger than the sample mean difference of 5 points. This provides a clearer difference between the two samples. Additionally, having the same standard deviation of 5 for both samples means that any difference in the means is purely due to chance and not influenced by differences in variability. Therefore, choice C provides the best option for a clear difference between the two samples.
