To find the average number of Variegated Fritillaries for the three years, we can follow a step-by-step approach:
1. Extract the Variegated Fritillary Counts:
- For 2009: 7
- For 2010: 95
- For 2011: 63
2. Calculate the Total Sum of Variegated Fritillaries:
[tex]\[
7 + 95 + 63 = 165
\][/tex]
3. Determine the Number of Years:
- The data covers 3 years (2009, 2010, and 2011).
4. Calculate the Average:
[tex]\[
\text{Average} = \frac{\text{Total Sum of Variegated Fritillary Counts}}{\text{Number of Years}} = \frac{165}{3} = 55
\][/tex]
Therefore, the average number of Variegated Fritillaries for the three samples is [tex]\( 55.0 \)[/tex].
As a result:
- The total number of Variegated Fritillaries counted over the three years is [tex]\( 165 \)[/tex].
- The average number of Variegated Fritillaries per year is [tex]\( 55.0 \)[/tex].
