    Tiger Shark Population

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Marine biologists in Florida are studying the tiger shark to determine the factors that are contributing to their diminishing population. Adult tiger sharks along the Atlantic Coast of Florida have a mean length of 11.5 feet with a standard deviation of 0.9 foot. Adult tiger sharks along the Gulf coast of Florida have a mean length of 11.9 feet with a standard deviation of 0.6 foot. Tiger shark lengths are normally distributed.

    20. The biologists need to capture 1 more adult tiger shark at least 13 feet in length for their study. Along which coast will the researchers have a higher probability of capturing the shark they need? Explain your reasoning.

    21. The biologists need to capture 1 more adult tiger shark less than 10.5 feet in length in order to complete their study. Along which coast will the researchers have a higher probability of capturing the shark they need? Explain your reasoning.
