A set of observations of independent variable (x) and the corresponding dependent variable (y) is given below.

Based on the data, the coefficient a of the linear regression model y = a + bx is estimated as 6.1. The coefficient b is ____________ . (round off to one decimal place)
    Correct answer is '1.9'. Can you explain this answer?

    We know that, normal equation for fitting of straight lines are
    ∑y = na + b ∑x
    and ∑xy = a ∑x + b ∑x2
    Here, n = 4
    So, 51 = 4a + b(14)
    188 = a(14) + b(54)
    ⇒ After solving, a = 6.1 and b = 1.9
