# A population data set produced the following information. N = 460, ∑x = 3920, ∑y = 2650, ∑x2 = 48,530 ∑xy = 26,570, Find the population regression line. alexespinosa

Regression line is given in the form of: y = a + bx

Working out 'b'  Σxy - [ΣxΣy]/N Σx² - [Σx]²/N   Working out 'a'

a = [∑y/N] - b[∑x/N]
a = [2650/460] - 0.264[3920/460]
a = 5.86 - 2.25
a = 3.61

Regression line equation is
y = 3.61 + 0.264x  ### Other questions on the subject: Math Math, 28.10.2019, JUMAIRAHtheOTAKU
