C3. Hypotheses Consider the following model for the proportion of endemic species on each of the Galapagos islands: proportioni = 50 | l log(areaZ-) + g (log(areaz-))2 | gnearesti + 54elevationz- | q Assume that all predictors have been standardized. Express each of the questions below as a pair of statistical hypotheses about the model. (Please be sure to include both the null and alternative hypotheses.) i. Does the proportion of endemic Species vary linearly in log-area (after adjusting for elevation and the distance to the nearest island)? ii. Is distance to the nearest island a signicant predictor of the proportion of endemic species (after accounting for elevation and log-area)? iii. Is log-area a signicant predictor of the proportion of endemic species (given distance to the nearest island and elevation)? iv. Are any of the predictors in the model signicant
