A team of forensic psychologists investigated whether the level of emotional remorse shown by a defendant impacts jury decision-making. They compared guilty versus not-guilty verdicts for defendants who showed either high remorse or no remorse during their trial. The researchers calculated a Chi-squared value of 2.95 with df=1df = 1df=1 for a two-tailed hypothesis.
Analyse the results of the Chi-squared test using the table below to show whether the defendant's emotional remorse significantly affected jury verdicts.
