5. Looking at your graph, do you think bagworm number is even among the sites? 6. When thinking about the categories associated with the sites (sites 1 and 5 are very close to junipers, sites 2 and 4 are < 100 m from junipers, site 3 is > 100 m from junipers), do you think there could be support for the hypothesis that distance to junipers might be influencing bagworm number on the trees in each site? Why or why not? 7. Now we will run an actual stat test to see if we can reject our null hypothesis. In order to know whether or not our null is supported, we will compare the number of bagworms we observed at each site to the number we would expect to see at each site, assuming each site has an equal number, given its surface area (m²). Because our sites were not all the same size, I have calculated the expected values and adjusted them according to surface area for each site. These expected values are listed for you in column K. Place your observed values from column G in column L for each site (paste special as values) and run an appropriate statistical test to determine whether what you observed was different from what you expected (use a one-tailed test for this). Run your test using the Basic Statistics Calculator. Copy the output to this tab and paste special as values. Make sure your output is labeled. Questions to answer about the statistical test: 8. Which inferential statistical test did you use? 9. What are your degrees of freedom (df) for this test? 10. What is the value of your test statistic (you can round to the nearest 100th place)? 11. What is the critical value, assuming a one-tailed test? 12. Was the null hypothesis supported or rejected and why? 13. What does this result tell you?

### Bagworm Data Analysis

#### Data Summary

The table consists of data collected on the presence of bagworms across different sites. Here's a detailed breakdown:

- **Bagworm Sightings (Y/N):** Indicates whether bagworms were observed (Y) or not (N).
- **Bagworm #:** Number of bagworms spotted.
- **Site Distribution:** Data is categorized based on five different sites.
- **% Bagworms:** Percentage of total bagworms found at each site.

#### Site Details

- **Site 1:**
  - Bagworms: 414
  - % Bagworms: 9.43%
  - Expected: 338.0033
  - Observed: 414

- **Site 2:**
  - Bagworms: 863
  - % Bagworms: 19.66%
  - Expected: 929.5875
  - Observed: 863

- **Site 3:**
  - Bagworms: 101
  - % Bagworms: 2.30%
  - Expected: 375.8202
  - Observed: 101

- **Site 4:**
  - Bagworms: 1050
  - % Bagworms: 23.92%
  - Expected: 1335.055
  - Observed: 1050
  
- **Site 5:**
  - Bagworms: 1961
  - % Bagworms: 44.68%
  - Expected: 1414.534
  - Observed: 1961

#### Total Data:

- Total Bagworms observed: 4389
- Combined percentage: 100%

#### Pie Chart Explanation

- **Title:** The Sites of Bagworm
- **Segments:**
  - Blue (Site 1) - 9%
  - Orange (Site 2) - 20%
  - Grey (Site 3) - 2%
  - Yellow (Site 4) - 24%
  - Light Blue (Site 5) - 45%

The pie chart visually represents the distribution of bagworms across the five sites. Site 5 displays the largest percentage at 45%, indicating a significant concentration of bagworms compared to other locations.
