The dynamics between Strongylocentrotus franciscanus red sea urchin, Strongylocentrotus purpuratus purple sea urchin and Haliotis cracherodis abalone population is complex, but simple in that they both compete for kelp as food. The proposed research hypothesizes that the optimum proportion of kelp to sea urchins in the environment of the black abalone will slow their extinction. The proposed research can offer data and information so that abalone extinction can be slowed.

Descriptive Statistics: Duration

Variable N N* Mean SE Mean StDev Minimum Q1 Median Q3 Maximum
Duration 430382 0 1309 12,7 8314 0,0 480 780 1260 1228320
Mean of “Duration” is 1309 minutes
Also we can calculate that among 430382 observations, there are 707 EndStations with the name “Queen Marys, Mile End”
Hence, the sample proportion is:
p=707430382≈0.001643=0.1643%
