QUESTION 10 In a study, a researcher conducted an independent samples t-test on a sample of 500 young people. The results yielded a p-value of 0.01. The researchers had set the level of significance at 0.05. Which of the following statement(s) about the p-value is/are NOT correct? (Select all that apply). The difference between groups was unlikely to have occurred by chance alone. The p-value was likely not affected by the sample size. O The researcher would conclude the difference between groups was statistically significant. This p-value indicates that there is a 99% chance that the alternative hypothesis is true. QUESTION 11 In a study exploring the effect of noise-cancelling headphones on patient anxiety in a large cohort of ICU patients (n=500), researchers found a statistically significant difference between those who used the headphones and those who did not. In considering clinical significance of these results, which of the following would the researcher be least likely to prioritize? O The numerical difference in anxiety scores between groups. Nurse perceptions of the headphones. O Patient and/or family perceptions of the effect of the headphones. O Nurse observations of the patient's behaviors or other similar variables
