Explanation:

Question 1

To find the favorite birdfeed, we look at the "Average Number of Birds" column. Sunflower has an average of 26, which is the highest among all birdfeeds.

We check the "Average Number of Birds" column. Milo and Nyjer (Thistle) both have an average of 4, which is the lowest among all birdfeeds.

We select the three birdfeeds with the highest average number of birds. Sunflower (26), Suet (15), and Safflower (12) have relatively high averages. Alternatively, Sunflower, Suet, and Millet (both Millet and Suet have an average of 15) are also good choices as they have high averages.

Answer:

Sunflower
