Hi there can any help me answer the following questions, stats is driving p the wall!!! ThanksMarks (out of 100) on Mathematics and English tests have means 45 and 50, respectively, and one student scores 40 in Mathematics and 60 in English. Given that the regression line for predicting English marks from Mathematics marks (a) passes through the point defined by the means, and (b) predicts this student’s English mark as 70, show thatthe regression line isE = 230 − 4 ×Mwhere E,M denote the English and Mathematics marks respectively. Further show that it is not sensible to use the regression line whenM < 32.5 or M > 57.5.2
