4.96 Multiple Sclerosis and Sunlight It is believed that sunlight offers some protection against multiple sclerosis (MS) since the disease is rare near the equator and more prevalent
at high latitudes. What is it about sunlight that offers this protection? To find out, researchers injected mice with proteins that induce a
condition in mice comparable to MS in humans. The control mice got only the injection, while a second group of mice were exposed to UV
light before and after the injection, and a third group of mice received vitamin D supplements before and after the injection. In the test
comparing UV light to the control group, evidence was found that the mice exposed to UV suppressed the MS-like disease significantly
better than the control mice. In the test comparing mice getting vitamin D supplements to the control group, the mice given the vitamin D da
not fare significantly better than the control group. If the p-values for the two tests are 0.472 and 0.002, which p-value goes with which test
