Problem 2: Expressive writing and physical health A team of researchers is interested in the effect on physical health of writing about thoughts and feelings associated with traumatic life events (Expressive Writing). The researchers recruit 32 undergraduate students to take part in the study and randomly assign them to be in an expressive Writing Group or a Control Group. Students in the expressive writing group are instructed to write four 20 - minute essays over four consecutive days about their most traumatic life experiences. Students in the control group write four 20 minute essays over consecutive days describing their plans for that day. One week later, the researchers ask the students to rate their overall level of physical health (on a scale 0 = very poor health to 100 = perfect health). EWG: 75, 86, 77, 91, 68, 74, 62, 93, 82, 79, 94, 56, 79, 86, 90, 97 CWG: 81, 76, 71, 70, 62, 50, 58,63, 76, 64, 65, 72,52, 59, 60, 61 The researchers were interested in identifying a positive or a negative health effect of expressive writing. Run the proper t test to see if this previous research is supported.
