lm vs. Poisson coeffients

A linear model and Poisson regression have been fit for you. Extract the coefficients for both models. Exponentiate the results from the Poisson regression. This is needed because the Poisson coefficients are estimated on link-scale, not the raw data-scale. Notice the relationship between the linear model coefficients and the Poisson regression coefficients.

You have been given the model lmOut, extract the coefficients using coef() and save as lmCoef.
You have been given the model poissonOut, extract the coefficients using coef() and save as poissonCoef.
Exponentiate the coefficients from poissonOut using exp() and save this as poissonCoefExp.
