typical day) and $$y=$$ GPA (cumulative GPA determined from university records) was $$r=?0.203$$. or lower GPAs? The value of the correlation coefficient is , which suggests that students who use a cell phone for more hours per day tend to have GPA's. values for the correlation coefficient between texting and GPA could have been the one observed? $$\begin{array}{l}r=?0.30\\ r=?0.10\\ r=0.10\\ r=0.30\end{array}$$ think that the value of the correlation coefficient for texts sent and texts received was close to $$?1$$, close to 0 , or close to $$+1$$ ? Explain your reasoning.
