(2 marks) Using the mean RT data for visual, auditory, visual+auditory stimuli in Lab1, calculate the correlation coefficients for the RT between all three pairs of stimuliusing Excel (1.5 marks). This should use the mean RTS for three conditions foryour entire lab (so a N of at least 15 participants, that your TA will provide). What isthe critical value necessary to determine if each of the correlation coefficient issignificant (0.5 mark).
