The COVID-19 pandemic has influenced the daily lives of healthcare workers, not only in terms of their physical health, but also their emotional and mental health. A 2022 peer reviewed study by Beverly, et al. examined the influence of virtual reality experiences on the subjective stress of frontline COVID-19 healthcare workers. The following ratings of subjective stress (on a 10-point scale from 1 of not stressed to 10 extremely stressed) for 10 participants are displayed in the table below. Please calculate the test statistic for the claim that the virtual reality experience decreased stress among frontline healthcare workers using a 0.05 significance level.
