1. Research has shown that stress can negatively impact individuals in various aspects of their lives. A researcher is particularly interested in investigating the relationship between stress and self-esteem among first-year students. They collect data from 8 students (n=8). Each student completes a questionnaire which includes both a stress and self-esteem scale. The collected data is presented below:

Perceived stress	Self-esteem scores
29	51
22	40
19	47
31	63
27	46
21	43
39	25
39	35

Following the hypothesis-testing process, investigate the relationship between stress and self-esteem by conducting a correlation. You are required to use a two-tailed test with an alpha level of 0.05. All calculations must be done manually (i.e., show all working). 15 Marks
