TEAM specialty †¦ TUNEUP (1 hour) †¦ REPAIR (actual time + materials) †¦ INSTALL (quoted time + materials). The coefficient of correlation r (98) = 0.882, p = 0.000 0.001, indicates that there exists a strong positive linear relationship between the variables APPOINTMENTS and OUTBOUND. The test statistic t (98) = 18.50, p = 0.000 0.001 indicates that the slope of regression between APPOINTMENTS and OUTBOUND is significant. The coefficient of determination R2 = 0.777 indicates that 77.7% of the total variation in the APPOINTMENTS isShow MoreRelatedRegression Analysis1445 Words   |  6 PagesA Term Paper On BUSINESS STATISTICS 1 Submitted To Dr. Md.
