Q19 [a] A researcher measures the relationship between the number of interruptions in class and time spent on task [in minutes]. Compute the Pearson correlation coefficient for the data below. Use your own paper to calculate the correlation coefficient; hang onto to it just in case. Note: The etext table is incorrect because of faulty formatting. Use the r distribution available in Blackboard. Below you will enter: 2.1 Mean for number of interruptions (x) 2.2 SS for number of interruptions 2.3 Mean for time spent on task (y) 2.4 SS,for time spent on task 2.5 Sum of Products (SP, SSry)
