Provide RationaleIs the relationship between perceived ethics confidence and physician collegiality clinically important?Provide RationaleIn a hypothetical study, perceived stress and perceived quality of life were correlated at Pearson r = 0.39. The sample size was N = 62, a = 0.05, and the data were examined with two-tailed test. Using the Table of Critical Values for Pearson r in Appendix B, determine if r = 0.39 is statistically significant.How did the study participants describe the patient care demands?
