Consider the following hypothesis test. . 2 _ 2 H0. 012 022 Ha: 01 at 0'2 (a) What is your conclusion if n1 = 21, 512 = 4.2, n2 = 26, and $22 = 2.0? Use a = 0.05 and the p-value approach. Find the value of the test statistic. 1:: Find the pvalue. (Round your answer to four decimal places.) State your conclusion. 0 Reject H0. We cannot conclude that 012 at 022. 2 2 #:0'2. 0 Do not reject Ho. We cannot conclude that 01 O Reject H0. We can conclude that 012 at 022. Q Do not reject H0. We can canclude that 012 at 022. (b) Repeat the test using the critical value approach. Find the value of the test statistic. l:l 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 statistic s [::I test statistic 2 State your conclusion. 2 O Reject H0. We cannot conclude that 012 02 . Q Do not reject H0. We cannot conclude that 012 at 022. ' O Reject Ho- We can conclude that 012 022. Q Do not reject Ho. We can conclude that 012 1: 022
