Do larger butterflies live longer? The wingspan, in millimeters, and the lifespan in the adult state, in days, were measured for 22 species of butterfly. Wingspan is the x-variable and lifespan is the y-variable. The results of computing the least-squares regression line on a TI Calculator are below.
