Question: You may need to use the appropriate technology to answer this question.Consider the following hypothesis test. H 0 : 1 2 = 2 2 H
You may need to use the appropriate technology to answer this question.Consider the following hypothesis test.
H0: 12 = 22
Ha: 12 22
(a)What is your conclusion if
n1 = 21,
s12 = 4.2,
n2 = 26,
and
s22 = 2.0?
Use
= 0.05
and the p-value approach.Find the value of the test statistic.Find the p-value. (Round your answer to four decimal places.)p-value = State your conclusion.Reject H0. We cannot conclude that 12 22.Do not reject H0. We cannot conclude that 12 22. Reject H0. We can conclude that 12 22.Do not reject H0. We can conclude that 12 22.(b)Repeat the test using the critical value approach.Find the value of the test statistic.State the critical values for the rejection rule. (Round your answers to two decimal places. If you are only using one tail, enter NONE for the unused tail.)test statistictest statisticState your conclusion.Reject H0. We cannot conclude that 12 22.Do not reject H0. We cannot conclude that 12 22. Reject H0. We can conclude that 12 22.Do not reject H0. We can conclude that 12 22.
