Question

Case Study # 1. A sample of 10 fish is randomly selected from a normally distributed population of Indian River Lagoon fishes. Each fish is weighed and measured and then dissected to remove the otoliths (or ear stones), which are also measured. The distribution of otolith length and fish mass is approximately normal. A statistical analysis of this case study shows the following results: T= 0.8386 (P <0.05) Otolith Length (mm) 150 300 Fish Mass (9) Figure Z. A scatter plot showing the relationship between mass (g) and otolith length (mm) of fish in the Indian River Lagoon.

Answer 1

5% Here calculated value of it tabualed value of t8,0.025 Hence we reject Ho at level of significance. 4 Conclusion - Hence we reject to at sto level of significano ince and conclude that there is correlati on between fish mass and otdiths length. Biological conclusion: The fish mass and otoliths leng th are positively correlated le change of fish mass and otoliths length are in some direction increases other also increases As one CS Scanned with CamScanner
