Dr. Smith examined whether length of court trials (X) predicts length of time for juries to come to decision (Y). She obtained the descriptive statistics and the correlation coefficient based on 4 cases. Mean SD N Length of Court Trials (days) 9.00 5.477 4 Length of Time (hours) 7,00 2.582 A The correlation between the two variable was .71. Given the means, SDs, and correlation, find an unstandardized intercept (a). O a = 7 - (.33 x9) = 4.03 O a = 9 - (.33 x 7) = 6.69 O a = 7- (1.50 x 9) = -6.5 O a = 9 - (1.50 x 7) = -1.5
