An honours psychology student at Harvard wanted to examine the association between mother's warmth and child's anxiety for his PSYC485 thesis. To do so, he selected a random sample of 82 participants from his department's participant pool and measured each participant's level of anxiety using the Beck Anxiety Index (BAI). He also measured each participant's mother's warmth by having each participant complete a 16-item questionnaire he found on the Internet. High scores on the BAI indicate high levels of anxiety and high scores on the "warmth" questionnaire indicate high degrees of maternal warmth. His results showed that the mean BAI score was 8.9931 with a standard deviation of 2.5691, and the mean score for mother's warmth was 11.2547, with a standard deviation of 3.1185 The correlation between BAI scores and mother's warmth was r=-.2518. Compute the slope of the regression equation predicting BAI scores from mother's warmth scores.
