Question:

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. Following are the results. image text in transcribed

a. Compute the least-squares regression line for predicting the lifespan from the wingspan.

b. Is it possible to interpret the y-intercept? Explain.

c. If the wingspans of two butterflies differ by 2 millimeters, by how much would you predict their lifespans to differ?

d. Predict the lifespan for a butterfly whose wingspan is 28.5 millimeters.
