To find the average number of Variegated Fritillaries (VFs) for the three samples, follow these steps:
1. Identify and List the Counts:
- For 2009: 7 Variegated Fritillaries
- For 2010: 95 Variegated Fritillaries
- For 2011: 63 Variegated Fritillaries
2. Calculate the Total Count:
- Sum the counts from each of the years:
[tex]\[
7 \, (\text{from 2009}) + 95 \, (\text{from 2010}) + 63 \, (\text{from 2011})
\][/tex]
- Add them together:
[tex]\[
7 + 95 + 63 = 165
\][/tex]
So, the total number of Variegated Fritillaries over the three years is [tex]\(165\)[/tex].
3. Calculate the Average Count:
- Divide the total count by the number of years (which is 3):
[tex]\[
\frac{165}{3} = 55.0
\][/tex]
Thus, the average number of Variegated Fritillaries over the three years is [tex]\(55.0\)[/tex].
So, the average number of Variegated Fritillaries for all three samples is [tex]\(55.0\)[/tex].
