Expert Solution
Step 1

3a) B. The proportion of swallows with shorter wings is increasing in the population.

As we can observe in the graph of mean wing length that the trend is decreasing for the overall population. Hence we can conclude that the proportion of swallows with shorter wings is increasing in the population.
