Abstract:
Blacktip sharks (Carcharhinus limbatus) form large seasonal aggregations numbering in the thousands. These aggregations are typically spotted from the air which makes it impossible to determine the sex and size distribution. We sampled C. limbatus that occur in large aggregations off the coast of southeast Florida. The aggregations were comprised primarily of adult male sharks (95.2%) that were of a similar size (170.8 ± 8.07 SD cm). This provides evidence of both size and sex segregations for this species during the overwintering phase of their annual migration.

01:24Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
