Answer 1

Answer to question# 8)

Part a)

The error variance of the model = Sum of square of error / df of error

we got SS error = 10.6

df of error = 4

Hence error variance = SSerror / df error

Error variance = 10.6/4

Error variance = 2.65

.

Part b)

Standard error of model fit = square root of error variance

Standard error of model fit = sqrt(2.65)

Standard error of model fit = 1.6279
