6. (10 points; hypothesis test for a difference of 2 means; Ch 7.2) Use the data from the previous question 5 to test whether there is a difference in mean reaction time between the "non repeating" and "repeating" stimulus. That is, test whether the mean difference is equal to 0 or not. Follow the 5-step procedure for testing a hypothesis. Use =0.01. It's OK to use R to calculate a p-value if you'd like
