In the study of human origins, anthropologists divide themselves into two camps, the "lumpers"(who argue that all the pieces of evidence are not all that different) and the "splitters"(who argue that the differences represent separate species). One anthropologist wondered if being a lumper or splitter was related to experience as an anthropologist. She gathered the data that follow. Analyze it and write a conclusion: $$\begin{array} { c c c c } & \text { Lumpers } & \text { Splitters } & \Sigma \ 5 \text { yrs. Experience } & 40 & 20 & 60 \ \Sigma & 50 & 50 & \end{array}$$
