I hop the solution

In a simple linear regression problem, the following statistics are calculated from a sample of 10 observations: Eri(ri - x)(yi - y) = 2250, Sex = 10, Line = 50, 21 1yi = 75. The least squares estimates of the slope and y-intercept are respectively: O 1.5 and 2.5 O 2.5 and -5.0 1.5 and 0.5 2.5 and 1.5 Clear my choice
