This question tests your ability to manipulate quantitative data and graph that data informatively. The tables below show the beak depth of finches on Daphne Major in the Galapagos Islands, taken from research by Peter and Rosemary Grant, as shown in the introduction video to this lab. The lefthand table shows beak depths of finches that did not survive a severe drought, and the righthand table shows beak depths of surviving finches.

Calculate the mean beak depth for non-surviving versus surviving finches and the standard deviation of the mean in the two cases. Construct a bar graph comparing the average (mean) beak depths of non-surviving versus surviving finches. Title your graph and label your axes, provide a y-axis numerical scale, and use the standard deviations of each (non-surviving versus surviving finches) to make an error bar showing the uncertainty of the mean beak depth for the two groups.
