Final Answer : A, Explanation :  A correlation coefficient of r(30) = .38 with a p-value less than .05 indicates a statistically significant positive relationship between using cell phones and walking into telephone poles. Therefore, the null hypothesis (which states that there is no relationship between the two variables) is rejected, and the research hypothesis (which states that there is a positive relationship between the two variables) is supported.
