A plot suggests that the expected value of thermal conductivity y is a linear function of 10⁴ · 1/x, where x is lamellar thickness.

(a) Estimate the parameters of the regression function and the regression function itself. (Round your answers to four decimal places.)

y = [answer]+ [answer]/X

Solution

sOL)

The Regression equation is y=a+bx

From Excel

The fitted Regressionequation is

y=14.3269 + 0.0005 (X)

B) when x=500

The fitted Regression equation is

y=14.3269 + 0.0005 (500)

y=14.577
