A researcher was interested in the effect of outdoor activity on mood. She hypothesized that spending time doing outdoor activity like walking in the forest would increase mood. She recruited 10 participants in her study. She had each participant walk a 2 km trail in the forest. Before and after the walk she had them rate their mood on a 5-pt Likert scale from 1 - very bad mood to 5 - very good mood. The data are reported in the table below. Mood Before Mood After 4 3 1 4 1 4 4 14 4 Copy or type the data into an Excel spreadsheet. Run the appropriate test to test the hypothesis at the 5% significance level (a = 0.05).
