Essay

life without their physical capture and handling. In a recent study of
bobcat (Lynx rufus) abundance, camera traps were placed at varying
distances from a road. The data on trapping success from 8 trapping
stations are presented in the table at right. The trapping success is
Remote camera trapping is used to detect and monitor elusive wild- $\begin{array} { | r | r | } \hline \begin{array} { c } \text { Distance } \\\text { (m) }\end{array} & \begin{array} { c } \text { Trap } \\\text { Success }\end{array} \\\hline 115 & 2.0 \\\hline 326 & 1.6 \\\hline 528 & 2.0 \\\hline 979 & 1.7 \\\hline 1252 & 1.9 \\\hline 1252 & 4.6 \\\hline 1459 & 5.7 \\\hline 2145 & 5.4 \\\hline\end{array}$ defined as the number of captures per 100 trap-nights.
-a) What is the least squares line for predicting trap success using
the distance from the road?
b) Sketch the least squares line on the
scatter plot. c) What is the value of $r ^ { 2 } ?$ Interpret this value in the context of this problem. $life without their physical capture and handling.

Calculate the residual for this trap site. e) Suppose that the trap sites you analyzed above are representative of the population of all trap sites. In general, do you think the linear model is a good model for these data? Justify your answer by appealing to the scatterplot and other summary statistics.$ d) One of the trap sites is 1459 meters from the road. Calculate the residual for this

Definitions:

The process of locating specific data, information, or files within a database or filesystem.

Share Information

The act of making data available to others, often through networked computers or storage systems, to facilitate communication or collaboration.

Default Gateway

The IP address of a Layer 3 device, such as a router, that is directly connected to its immediate network. It tells a device on its network where to send a packet destined for a remote network.

IP Address

A type of network adapter address used when multiple networks are linked. Known as a Layer 3 address, in IPv4 it is a 32-bit binary number with groups of 8 bits separated by a dot. This numbering scheme is also known as dotted-decimal notation. Each 8-bit group represents numbers from 0 to 255. An example of an IPv4 IP address is 113.19.12.102. Also see IPv4 and IPv6.
