Establishing the properties of materials is an important problem in identifying a suitable substitute for biodegradable materials in the fast food packaging industry. Consider the following data on product density (g/cm3) and thermal conductivity K-factor. Thermal Product Density
Conductivity x
y
0.0480 0.1750
0.0525 0.2200
0.0540 0.2250
0.0535 0.2260
0.0570 0.250
0.0610 0.2765
For the data above perform the following: (not minitab, do by hand)
a) Estimate the intercept and the slope write the regression line
b) Compute the residuals
c) Compute SSE and estimate the variance
d) Find the standard error of the slope and intercept coefficients.
