19. a researcher measures the relationship between the number of interruptions in class and time spent on task (in minutes). answer the following questions based on the results provided. 1. compute the pearson correlation coefficient. 2. multiply each measurement of interruptions by 3 and recalculate the correlation coefficient. 3. divide each measurement in half for time on task and recalculate the correlation coefficient. 4. true or false: multiplying or dividing a positive constant by one set of scores (x or y) does not change the correlation coefficient. note: use your answers in (a) to (c) to answer true or false.
