An investigator tests a claim that vitamin C alters the severity of common colds. To eliminate variability due to different family environments, pairs of children from the same family are randomly assigned to either a treatment group that receives vitamin C or a control group that receives a placebo. Each child estimates, on a 10 point scale, the severity of their colds during the school year. The following scores were obtained from 10 pairs of children. What should the investigator conclude?
