12. Information on peptides identified in the brain of different animals is of interest to researchers. An experiment is carried out to compare the content of peptides in the brains of two species of fish. Brains of dogfish an skates were quickly removed from fish freshly caught and the peptides in the brain determined by electrophoresis. At the 10% level of significance, which of the following are the correct null and alternative hypotheses to determine if a there is a difference between the average peptide level in the brain tissues of the two species? (A) H, :4, - H, = 0 vs H,:H,- H,# 0 Test Statistic, t: Critical t: P-Value: -1.3870 * 2.091813 0.1814 (B) H, :H, - H, = 0 vs H :H, - H,< 0 (C) H, :µ, – µ, = 0 vs H¸:µ, - H,> 0 Degrees of freedom: 19.1641 95i Confidence interval: -0.2189664 < ul - µ2 < 0.0443664 (D) H, :H, - H, < 0 vs H¸ :µ, - H,> 0
