Answer 1

1. If the average beak depth of the finch population has changed along with population size between 1974 and 1981.

2. Hypothesis: Average beak depth increased among the finches after 1976 when a drastic reduction in the finch population size is noted.

(Till 1976, the population size was 750 or more, and average beak depth was within 9.6 mm. But after 1976 there was a drastic decline in the population which got reduced to 275 and further kept declining, along with an observed increase in beak depth (increased to around 10 mm). This might indicate some natural calamity in 1976 which reduced a population and altered the normal conditions of the environment. Due to this the finches had to adapt to the changed situation by increasing their average beak length.)

3. For the graph, take x-axis as the Year (1974 - 1981. Mark each bar as one year. Take the average beak depth (mm) as the y-axis. Draw bars representing the average beak depth in each year on x-axis. Write the population size above the bars (for example n=275)
