Question
Consider the hypothesis test Ho: o = o2 against H₁: o <o2 respectively. Suppose that the
sample sizes are n₁ = 5 and n₂ = 10, and that s2 = 23.2 and s2 = 28.8. Use a = 0.05. Test the
hypothesis and use the confidence interval to support the conclusion
O a. Because 0.1666 < 0.806. Reject the null
hypothesis.
O b. Because 0.1666 < 0.806. Do not reject the null
hypothesis.
O c. Because 0.1666 < 0.806. Do not reject the null
hypothesis. Because 1 is contained within the
interval, there is no significant differences in the
variances
O d. None among the choices
