I' An honours psychology student at Concordia 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 EM indicate high levels of anxiety and high scores on the \"warmth" questionnaire indicate high degrees of maternal warmth. His results showed that the'mean BAl 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 BA! scores and mother's warmth was r= -.2518. Compute the mpg of the regression equation predicting BAI scoi'es from mother's warmth scores
