Compose answers to the questions below and save the file as a backup copy in the event
that a technical problem is encountered while attempting to submit the assignment. Make
sure to run a spell check.

You will be submitting your answers to the lab assignment in two parts. The first part of
the lab assignment consists of the laboratory exercise questions. The second part of the
lab assignment is the application question. The first textbox on the submission page
corresponds to the first part of the lab. Be sure to paste the laboratory exercise questions,
with your answers, into this textbox. The second textbox on the submission page will be
for your response to the application question.

LABORATORY EXERCISE QUESTIONS

~~1.

Answer the following turtle population questions:

POPULATION GROWTH

3

a. Using random sampling technique, select 3 grid segments for a sample taken
from the plot above. List the 3 grid segments you selected. (1 point)

Grid A1

Grid A2

Grid B2

b. Based on your sample, what is the average number of turtles per grid segment?
(1 point)

For Grid A1 there are 4.5 turtles

For Grid A2 there are 4 turtles

For Grid B2 there are 4 turtles

c. The plot represents an entire beach and each dot represents a turtle. Calculate
the estimated turtle population on the entire beach based on the 3 random grid
segments in your sample. (1 point)

Based on Grid A1 the total number of turtles is 4.5 x 6 = 27 turtles

Based on Grid A2, the total number of tattles is 4 x 6 = 24 turtles

Based on Grid B2, the total number of turtles is 4 x 6 = 24 turtles

POPULATION GROWTH

4

d. Count the total number of turtles on the beach. List that total. From this actual
count, what is the average number of turtles per grid segment? Show your
work. (1 point)

➢ The total number of turtles is 28
➢ Based on this total, the number of turtles per segment = 28 / 6 =
4.6667 turtles.
