Q7. Exercise 2: A random sample of the number of silver maple trees in a forest area that measures 5 miles by 5 miles. The number of trees counted per sampling grid is shown below. Given the data below, what is the estimated population size of silver maple trees in this 5 by 5 mile forest tract? Show your work on Tab 2 of the excel spreadsheet. 7 3 5 11 9 Q8. Exercise 3: Mark-release-recapture (MRR) Refer to Tabs MRR#1-3 to complete the next 3 questions. Remember to upload the spreadsheet to your student folder for grading. To demonstrate the MRR method, do the following: Step 1. Gather 30-100 small items (beans, beads, pennies, etc.) and some tape or a magic marker, and place a subset of them in a bag without counting them.Step 2. Capture l \"animals\" by removing them randomlyr from the bag. Step 3. Place a mark on them using tape or a dot of ink. This is the mark step of the MRR method. Step 4. Return the It] marked \"animals" to the container; this is the release step of the M method. Step 5. With your eyes closed, select 15 \"mimals'\" from the bag one at a time. This is the recapture step of the LIIRR method. Step ti. Record the number of \"animals\" captured that have a mark {record your data in Ex. # 1 tab of the spreadsheet]. Step T. Return the \"animals" to the bag and repeat steps 5 and 6 nine times for a total of It} recapture events. Step S. Record the total number captured and the number recaptured with a mark.
