In an experiment to compare two pain relievers, seven subjects took one of the two pain relievers (randomly selected) for two weeks, then switched to the other for another two weeks. They rated their pain level from 1 to 10, with larger numbers representing higher levels of pain. The researchers want to know if there is a difference in the mean level of pain for the two pain relievers. Suppose the p-value for the test is 0.2199. Which of the following is the best conclusion based on this result?

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
