Transcribed Image Text:Consider the hypothesis test Ho: o = o₂ against H₁: o² <o2 respectively. Suppose that the
sample sizes are n₁ = 5 and n₂ = 10, and that s = 23.2 and s² = 28.8. Use a = 0.05. Test the
hypothesis and use the confidence interval to support the conclusion
a. Because 0.1666 < 0.806. Do not reject the null hypothesis.
O b. 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
c. None among the choices
O d. Because 0.1666 < 0.806. Reject the null hypothesis.
