Answers: See each answer below:
1) 20% of 41 = 8.2 (0.2 x 41) Therefore, we would round it to 8 birds that were chickadees.
2) 4 out of the 21 birds were finches. 4 / 21 x 100 19%. About 19% of the birds were finches.
3) According to the graph, only 4 birds spotted were finches.
4) The two birds that were spotted the least were blue birds and cardinals, because they had the lowest numbers.
