I neee A-D answered and also question #2

a. Using random sampling technique, select 3 grid segments for a sample taken from the plot above. List the 3 grid segments youselected. (1 point b. Based on your sample, what is the average number of turtles per grid segment? (1 point) 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) c. d. Count the total number of turtles on the beach. From the actual count, what is the average number of turtles per grid segment? Show your work (I point) 2.Briefly explain why biologists use sampling rather than counting all members of the population of interest. (5 points)

Explanation / Answer

a. I have selected A1, B1, C1 grids.

b. Number of turtles in each grid:

A1 = 4; B1 = 2; C1 = 3

Average = (A1 + B1 + C1) / 3 = (4+2+3)/3 = 9/3 = 3

c. Population grid = 9

Estimated populaiton = Average * population grid = 3*9 = 27

d. A2 = 4; B2 = 4; C2 = 2; A3 = 3; B3 = 3; C3 = 2

Total number of turtles = 4+2+3+4+4+2+3+3+2 = 27

Average = Total number of turtles / Total number of grids = 27/9 = 3

2. Sampling is used for the following reasons:
