Question

You wish to test the following claim (HaHa) at a significance level of α=0.002α=0.002.

Ho:μ1−μ2=0Ho:μ1-μ2=0
Ha:μ1−μ2>0Ha:μ1-μ2>0

You obtain a sample of size n1=99n1=99 with a mean of ¯x1=62.9x¯1=62.9 and a standard deviation of s1=6.5s1=6.5 from the first population. You obtain a sample of size n2=51n2=51 with a mean of ¯x2=58.4x¯2=58.4 and a standard deviation of s2=7.8s2=7.8 from the second population.

You will need to determine whether or not to pool so you will use the correct df.
