relationship between a number of student complaints (x) and failure rate (y) was studied in 1500 female university students by using the least-squares criterion. The following equation of line was obtained from this study: -0.00127 + 0.0180x The above equation implies that: A. on average it takes 1.8 complaints to increase failure rate by 1% В. each student complaint increases failure rate by 1.27% С. each complaint increases failure rate by an average of amount of 1.8% D. each complaint increases failure rate by exactly 0.018
