Chapter 3: Q 13. (page 172)

Manatees are large, gentle, slow-moving sea creatures found along the coast of Florida. Many manatees are injured or killed by boats. Here is a scatterplot showing the relationship between the number of boats registered in Florida (in thousands) and the number of manatees killed by boats for the years 1977 to 2015.13Isr>0orr<0? Closer to r=0orr=±1?Explain your reasoning.

Short Answer

Expert verified

Data points are following the linear positive pattern which implies that the correlation is greater than 0 and closer to 1 that is, r>0 and closer to 1

Step by step solution

Explanation

The scatter plot is a graph that shows the association between two variables. It displays the level of correlation between two variables, known as the dependent and independent variables.

If the data points in the scatter plot create a linear pattern with a positive slope, the relationship between the variables is said to have the perfect positive.

The data points in the presented graph follow a linear positive pattern, indicating that the correlation is bigger than 0 and closer to 1 i.e., r>0 and closer to 1
