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
