Essay

Test the claim that the paired sample data is from a population with a mean difference of 0. Assume the
samples are random and dependent, and the populations are normally distributed. Use $\alpha = 0.05 .$ $$\begin{array} { c | r r r r r } \text { A } & 30 & 28 & 47 & 43 & 31 \\\hline \text { B } & 28 & 24 & 25 & 35 & 22\end{array}$$

Microevolution

Evolutionary change within a species or small group of organisms, especially over a short period.

Hybrid Inviability

A postzygotic reproductive isolating mechanism in which the embryonic development of an interspecific hybrid is aborted.

Mutation

A change in the DNA sequence within an organism's gene or chromosome, leading to variations in trait expression and possibly to different phenotypes.
