Question

Situations: Read the situation below and design an experiment. A: John Smith has been hired by the city of Virginia Beach to investigate the recent resort's coast. He has a budget of $40,000, a 25 foot boat, and three graduate student assistants to help him. A shark attacks off the helicopter has also been donated by a local television station, should he need one. 1. List 2 hypotheses John and his crew may have come up with for the recent shark attacks. a. If b. If , then then 2. Pick one of the two hypotheses and determine the following: a. Control Group: time of year when elephant seals are not present or another area with no elephant seals b. Experimental Group: times/areas when/where elephant seals vary c. Dependent Variable: d. Independent Variable: 3. What type of data do you think John will collect (What will be the results of the experiment)? 4. What conclusions will John be able to make from the results of the experiment?

Explanation / Answer

1 . List 2 hypotheses jhon and his crew may have come up with for the recent shark attacks.

a.If shark attacks are related to the number of elephant seals in a certain area, then shark attacks will increase as elephant seal numbers increase.

b.If swimmers wear bright colored swimming suits, then sharks will attack

2. Pick one of the two hypotheses and determine the following:

a. Control Group: time of year when elephant seals are not present or another area with no elephant seals

b. Experimental Group: times/areas when/where elephant seals vary

c. Dependent Variable: number of shark attacks

d. Independent Variable: number of elephant seals

3. What type of data do you think John will collect (What will be the results of the experiment)?

Shark attacks (distance from shore) vs number of elephant seals (mature and juvenile)

4. What conclusions will John be able to make from the results of the experiment?(depends on hypothesis we can give choose various answers)

Due to the increse in number of elephant seals in that area shark attacks increased.
