Question
Consider the hypothesis test Ho: M₁ = μ₂ against H₁: M₁ M₂. Suppose that sample sizes are n₁ = 15 and n₂ = 15, that x₁ = 4.7 and ₂ : x₂ = 7.8, and that s² = 4 and s2 = 6.25. Assume that o2 and that the data are drawn from normal distributions. Use a = 0.05. Test the 4.7 and 0₁ = hypothesis. a. Because -3.75 -2.048. Fail to reject the null hypothesis at a = 0.01 O b. None among the choices O c. Because -3.75 -2.048. Reject the null hypothesis at a = 0.05 O d. Because -3.75 -2.048. Fail to reject the null hypothesis at a = 0.05
