Merchandise loss due to shoplifting, damage, and other causes is called shrinkage. Shrinkage is a major concern to retailers. The managers of H.R. Merchandise think there is a relationship between shrinkage and number of clerks on duty. To explore this relationship, a random sample of 7 weeks was selected. During each week the staffing level of sales clerks (X) was kept constant and the dollar value (Y, in hundreds of dollars) of the shrinkage was recorded. The results are summarized as follows: top enclose x = 11.143, top enclose y = 18.71, sx = 2.410, sy = 7.59, r = -0.963, SS(residual) = 24.82 In the linear regression of Y on X, y = b0 b1 x, what is the value of b0?
