4. Researchers have conducted a study and determined that the relative risk for developing a cold for
individuals taking vitamin C is 0.47 when compared to the number of participants in the study who
developed a cold while not taking vitamin C. This is an indication of which of the following?

vitamin C makes people more susceptible to catching a cold.

vitamin C has a protective effect, making them less likely to catch a cold.

vitamin C has a protective effect, making them less likely to catch a cold.
D) Only relative risk ratios above one are statistically significant, a relative risk ratio below one indicates
there is no difference between the individuals who take vitamin C and those individuals who do not.
