Question

You have been provided with data on the percentage cover and average height of Thalassia testudinum (Turtle grass) along a 50m transect running from the shoreline out to sea at Crandon Park beach. Sampling was conducted using the line transect sampling technique Based on observations at Crandon Park we could put forth the following questions: ) Dors the percentage cover of Thalassia testudinum (Turtle grass) change with distance from n) Does the average beight of Thalassia tstuinm Turtl grass change with ditance froam the shore? the shore? 17.What are the variables in the example above? (2 pts) The variables in the example are the percentage cover, the average height of Thalassia testudinum and the distance along transect running 18.What is the sample collected? (2 pts) The sample collected is the heights of Thalassia testudinum along a 50 m transect running from the sboreline to sea at Crandon Park beach. 19.What is the population? (2 pts) The population is all the Turtle grass at Crandon Park beach. 9/20/2017 PrtSc Insert De F12 FTO 6

Explanation / Answer

17. Percentage cover, average height of turtle grass and distance from the shore are the 3 variables under consideration.

18. Sample consists of data on the % cover and avg. height of turtle grass along a 50m transect running from the shoreline out to sea at Crandon Park beach.

19. Population : All the turtle grasses at Crandon Park beach.

20. i)H0i : %cover of turtle grass and distance from shore are uncorrelated.
H1i : not H0i
ii)H0ii : Average height of turtle grass and distance from shore are uncorrelated.
H1ii : not H0ii

21. Since p-value > 0.05, we cannot reject the null hypothesis at 5% level of significance and conclude that Average height of turtle grass and distance from shore are uncorrelated.

22. If the grass height is correlated with the distance from shore, then accordingly the grass can be planted keeping in mind the distance from the shore.
