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

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.

Briefly explain why biologists use sampling, rather than individually counting all

members of the population of interest. (5 points)

There are a number of good reasons why sampling is preferred rather than counting

the entire population. Some of these reasons are;...
