Last year, rural communities in Canada experienced several severe natural disasters. In particular, research psychologists were interested in the psychological effects of the devastating
fires in Nova Scotia. Specifically, the researchers were interested in how hopeful people felt after the fires. The researcher randomly selected 10 people for this community to complete a short questionnaire. The key item on the questionnaire asked how hopeful they felt, using a 7- point scale from extremely unhopeful (1) to extremely hopeful (7).The researcher wanted to know whether the ratings for hopefulness for people who had experienced the fire would be consistently lower than the known population who had an average hopefulness of 4. Test at an alpha at 0.05 and use all the steps of hypothesis testing for full marks. Here is the data: 5,3,6,2,7,6,7,4,2,5.
