A real world statistics example
Marine biologists warn that the growing number of powerboats registered in Florida threatens the existence of manatees. For years from 1985 to 2000, given that

Identifying the names of the explanatory and response variables appropriate for the context.
From the given information, Let X- represents the boating registration and is termed as independent variable. (Explanatory variable).
Let Y -represents the manatee deaths and is termed as dependent variable. (Response variable)
Making a scatter plot of these data to describe the association.
The above scatter shows the strong association between Boat Registration and Manatee death. Since in the chart, the plots are scattered closely.
Finding the correlation between the boat registrations and manatee deaths
This can easy to calculate by using Excel Tool (Tools ...
The solution examines real world statistics examples. The statistical null and alternative hypothesis is stated.
