Multiple Choice
Identify the choice that best completes the statement or answers the question.

1.

A relatively new hybrid species between a giraffe and a zebra called a Okapi is proliferating in a region of Africa. A scientist studied a herd for several years and found the following population statistics:


What year would [P₂] describe the population for?

a.	2020	c.	2030
b.	2028	d.	2038

2.

A new species of shark named “Sixgill” was discovered by a marine biologist in the Pacific ocean with a small dorsal fin. The biologist collected data in Hawaii and in a specific region of the ocean was able to estimate the following data and statistics about a group of the this species near Hawaii.


If the data and statistics are accurate above for the next few decades, how many 0-7 year old sixgill sharks will be in this area in the year 2032?

a.	Approximately 30	c.	Approximately 40
b.	Approximately 35	d.	Approximately 45

3.

A relatively new hybrid species between a giraffe and a zebra called a Okapi is proliferating in a region of Africa. A scientist studied a herd for several years and found the following population statistics:


Using the above data, which matrix below would be best to use for the Growth or Leslie matrix [L]?

a.		c.
b.		d.

4.

A new species of shark named “Sixgill” was discovered by a marine biologist in the Pacific ocean with a small dorsal fin. The biologist collected data in Hawaii and in a specific region of the ocean was able to estimate the following data and statistics about a group of the this species near Hawaii.


Using the above data, which matrix below would be best to use for the initial population matrix [P₀]?

a.		c.
b.		d.

5.

A new species of frog named “Hyalinobatrachium Dianae” was discovered by herpotologists in Costa Rica. The researcher collected data in Costa Rica and was able to estimate the following statistics about a group of this species near a lake.


If the data above remains consistent, how many births could you expect this group to have over the next 2 years?

a.	Approximately 38	c.	Approximately 62
b.	Approximately 52	d.	Approximately 66

6.

A new species of dwarf crocodile may be evolving in Africa, the orange cave crocodile. A researcher was studing a small group in a remote region and collected the following population data for the year 2018.


For this population, which matrix operations would determine the population matrix for 2042 using an initial population matrix [P₀] and a Leslie Matrix [L]?

a.		c.
b.		d.
