A marine biologist is using a submersible to count the number of a particular species of fish in a designated transect of a coral reef. The fish are known to be randomly distributed and the average number of fish per transect is relatively constant. Which of the following is the most appropriate reason to use the Poisson distribution to model the number of fish counted?

A team of marine biologists is studying the length of a specific fish species in a large, heterogeneous population. Due to the high number of juveniles, the true population distribution of fish of fish length is known to be positively skewed. To estimate the population's true mean length, the team designs two sampling protocols : Protocol A involves taking 100 random samples, each of size n = 10. Protocol B involves taking 100 random samples, each of size n = 50. For each protocol, they calculate the mean length of the samples. Given the Central Limit Theorem, which of the following statements about the "sampling distribution of the sample means" is most accurate?
Answer
A. The sampling distribution for Protocol B will be approximately normal with a smaller standard error than the sampling distribution for Protocol A
74
A fishery scientist uses a least squares regression to study the relationship between the number of fishing days (x) and the total income (y) from sixteen fishing boats.

A fishery scientist models the growth of two different fish populations, Species X and Species Y, using the length-weight relationship W = aLᵇ. For Species X, the calculated parameters are a = 0.025 and b = 3.2. For Species Y, the parameters are a = 0.045 and b = 2.8. Assuming both populations are healthy, what is the most accurate conclusion that can be drawn from these parameters?
Answer
D. Species X is experiencing positive allometric growth, meaning it is becoming relatively heavier for its length as it grows. Species Y is experiencing negative allometric growth, becoming more streamlined
