Question: For the horseshoe crab data, fit a model using weight and width as predictors. Conduct (a) A likelihood-ratio test of H 0 : 1

For the horseshoe crab data, fit a model using weight and width as predictors. Conduct

(a) A likelihood-ratio test of H₀: β₁ = β₂, = 0,

(b) Separate tests for the partial effects. Why does neither test in part (b) show evidence of an effect when the test in part (a) shows strong evidence?
