The propagation of electromagnetic waves through material is dependent on the material's dielectric properties. A study was done to determine the relationship between dielectric constant (x) to air void percentage (y). The output of the data is shown below: Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Lower 95.0% Upper 95.0% Intercept 4.858691 0.059768 81.29252 2.28E-22 4.731988 4.985393 4.731988 4.985393 X Variable 1 -0.07468 0.009923 -7.5256 1.21E-06 -0.09571 -0.05364 -0.09571 -0.05364 You believe that the true average change in dielectric constant would be at least 0.
