(1 point) Suppose you needed to test the claim that the two
samples described below come from populations with the same mean.
Assume that the samples are independent simple random samples.
Sample
1: n1=8, x¯¯¯1=26.8, s1=3.99n1=8, x¯1=26.8, s1=3.99
Sample
2: n2=17, x¯¯¯2=24.3, s2=5.23n2=17, x¯2=24.3, s2=5.23
Find:
(a) The test statistic is
(b) The estimated degree of freedom is
