Please help me answer/perform the following with complete solution, I am really bad at STATS :

3. Use the given paired data to find the equation of the regression line. a) x | 2 | 3 1 1 1 2 1 1 1 y | 3 | 1 1 5 1 4 1 6 1 b) x1 1 3 | 4161 8 1 y 1 5.0 | 7.5 | 11.3 | 14.9 | 19.3 | 5. The following statistics are collected and summarized from a study of the factors affecting success in differential and Integral Calculus for 8 randomly selected B.S. Math students. X is the score obtained in algebra placement test while y is the score obtained in calculus achievement test. Ex = 165 Zy = 1334 Exy = 29,611 Ex2 = 3855 Zy= = 241,394 Exy = 29,611 X = 20.625 y = 166.75 a) Find m and b in the linear regression equation y = mx+b b) If a student got a score of 40 in Algebra, what will be his score in Calculus? 6. Use the given data in number 5 and compute the Se
