A study was conducted to examine the impact of speaking in public on college students. A class of 15 students participated in the study. At the beginning of a lecture the students recorded their systolic blood pressure. During the lecture the instructor called on each student to stand and answer questions about topics in the lecture. After speaking the students once again recorded their blood pressure. The resulting values are given below along with summary statistics. We are interested if the blood pressure increased because of speaking. Provide the test statistic value in the box below. Use 3 decimal places.
