Population 1 21 Population 2 19 n Use the given statistics to complete parts (a) and (b). Assume that the populations are normally distributed. (a) Test whether 14 > H2 at the a = 0.05 level of significance for the given sample data. (b) Construct a 99% confidence interval about 14-12 х 45.2 42.1 S 3.8 12.7 OBER 2 ו"זיע" Uri 2 H₂ : Hq = H2 U12 H:H=42 H₂:14 <H2 Find the test statistic for this hypothesis test 1.02 (Round to two decimal places as needed.) Determine the P-valce for this hypothesis test. .159 (Round to three decimal places as needed.) State the conclusion for this hypothesis test. O A. Do not reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that > H2 B. Do not reject Hy. There is not sufficient evidence at the a = 0.05 level of significance to conclude that 1412: C. Reject Ho. There is not sufficient evidence at the a=0.05 level of significance to conclude that > H2 D. Reject Ho. There is sufficient evidence at the a= 0.05 level of significance to conclude that , >12 (b) The 99% confidence interval about # -Hy is the range from a lower bound of to an upper bound of (Round to three decimal places as needed.)
