A Study Was Done to Determine If a Correlation Exists

question 54

Short Answer

A study was done to determine if a correlation exists between age of first arrest and the number of years of education an inmate had. A random sample was selected from the male population of a certain house of correction and their first-arrest ages were tallied along with their years of education. $$\begin{array}{l}\text { Subj\#} &\text { Age first arrest }&\text { Education Years }\\ 1 & 15 & 8 \\2 & 17 & 9 \\3 & 32 & 12 \\4 & 25 & 11 \\5 & 42 & 16 \\6 & 18 & 11 \\7 & 20 & 10 \\8 & 19 & 9 \\9 & 20 & 11 \\10 & 16 & 10\end{array}$$
