1.  Two independent samples are taken from two distinct populations whichproduce sample means, standard deviations as ̄x1= 104.6, ̄x2= 92.9,s1= 4.8,s2= 6.9,n1= 26,n2= 19.If we use min(n1−1,n2−1) as the d.f., what t critical value would you usein constructing a 90% confidence interval forμ1−μ2?a).  2.101; b) 1.734; c) 1.708; d) 1.645
