Round to 2 decimal places.

1.Participants saw a series of words on a computer screen. Each time, a word (either relating to a positive emotion or a negative emotion) was presented on a screen for 1500ms. Researchers asked participants to press the "A" key as quickly as possibly if they saw a positive word and the "L" key if they saw a negative word. The response is reaction time in milliseconds (i.e., how long it took the subject to make a response). Use an appropriate test statistical method to answer the question: Did the reaction time differ between the two types of words?
