When a least squares line is fit to the 12 observations in t

When a least squares line is fit to the 12 observations in the labor cost data, we obtain SSE = 1,043,412.2880. Calculate s2 and s. (Round your answers to 5 decimal places.)

s2 =

s =

Solution

As

s^2 = SSE/(n-1) = 1,043,412.2880 / (12-1) = 94855.66255 [ANSWER]

*****************

Also,

s = sqrt(s^2) = sqrt(94855.66255) = 307.9864649 [ANSWER]
