Imagine that we have taken samples from a pair of populations and we're using an unpaired homoscedastic t-test to determine whether their means are equal or not. Q1. If the sample sizes are both 6 and the sample variances are 9, what is the minimum difference between the sample means we would need to observe to decide that the population means are significantly different? Q2. If the sample sizes are both 12 and the sample variances are 9, what is the minimum difference between the sample means we would need to observe to decide that the population means are significantly different? Q3. Imagine a pair of populations with standard deviations of 3.1 and means that differ. If we take a pair of samples of equal size which give us the exact same standard deviation and mean values as the population, and we're using an unpaired homoscedastic t-test, what is the minimum number of data values in each sample to detect a difference of 2.4? (Provide this to the nearest integer) Min. diff. = ??? Min. diff. = ??? Min. n = ???
