Question

Find the critical value, $t_0$, to test the claim that $mu_1 < mu_2$. Two samples are randomly selected and come from populations that are normal. The sample statistics are given below. Assume that $sigma_1^2 = sigma_2^2$. Use $alpha = 0.05$. $n_1 = 15$, $n_2 = 15$, $ar{x}_1 = 25.2$, $ar{x}_2 = 27.75$, $s_1 = 2.9$, $s_2 = 2.8$ A. -1.313 B. 0.683 C. -1.701 D. 2.467

Find the critical value, t0, to test the claim that ̑̑1 < ̑̑2. Two samples are randomly selected and come from populations that are normal. The sample statistics are given below. Assume that ̑1² = ̑2². Use ̑ = 0.05. n1 = 15, n2 = 15, x̄1 = 25.2, x̄2 = 27.75, s1 = 2.9, s2 = 2.8. A. -1.313 B. 0.683 C. -1.701 D. 2.467
