The regression line, alongwith the plotted data-points, is as follows- The linear regression line passes through all points, and the value of the correlation coefficient is 1 (that is, perfect correlation). Thus, it is concluded that there is a perfect linear association between the given data sets. For set B, a linear regression line of Y against X needs to be plotted. The regression line, along with the plotted data-points, is as follows- The linear regression line lies close to most points, and (2.4, 2.6) is an anomaly.

...Statistical genetics Genetic association is an event that involves a number of traits in a population of individuals. The aim of genetic association is to find out whether genotype frequencies or single-locus alleles have a difference when comparing a set of individuals. The main foundation for genetic association is the ability to compare genotypes directly. The occurrence of genetic association can be between phenotypes that include characteristics such as height. Genetic association can also occur between single nucleotide polymorphism as well as genetic polymorphism (Arboretti 345). Genetic association assists in finding out if a trait associates with a genetic...
