an you tell how old a lobster is by its size? This question was investigated by the authors of a paper that appeared in the Biological Bulletin (August 2007). Researchers measured carapace (the exterior shell) length of 27 laboratory-raised lobsters of known age. The data on x = carapace length (in mm) and y = age (in years) in the following table were read from a graph that appeared in the paper. Age CarapaceLength Age CarapaceLength Age CarapaceLength 1.00 63.32 1.82 118.25 2.93 147.82 1.00 67.50 2.18 108.24 2.92 140.17 1.00 69.58 2.18 109.64 2.92 135.73 1.00 74.41 2.17 117.99 2.92 121.81 1.42 80.32 2.17 123.81 3.17 141.30 1.42 81.80 2.33 138.47 3.41 151.73 1.42 84.59 2.50 133.95 3.42 145.78 1.82 105.07 2.51 124.25 3.75 147.21 1.82 106.16 2.50 123.51 4.08 152.04 (a) Construct a scatterplot of these data, and then find the equation of the least squares regression line that describes the relationship between y = age and x = carapace length.
