when a least squares line is fit to the 19 observations in t

when a least squares line is fit to the 19 observations in the labor cost data, we obtain SSE= 706.7624

calculate s(squared) and s (round tour answers to 4 decimal places)

Solution

n = 19
SSE = 706.7624

s^2 = SSE/(n-2)
= 706.7624/17
= 41.5743

standard error of estimate,s = sqrt(41.5743)
= 6.4478
