Question:

H_a: μ₁ ≠ μ₂, α = 0.10, n₁ = 11, n₂ = 14

Use Table 5 in Appendix B to find the critical value(s) for the alternative hypothesis, level of significance a, and sample sizes n₁ and n₂. Assume that the samples are random and independent, the populations are normally distributed, and that the population variances are

(a) Equal
