A medical researcher experimented with the effects of calcium intake on the healing time of broken bones. People who had similar broken bone injuries were divided randomly into two groups, one of which received a calcium supplement and one of which received a placebo. The data showed that there was no significant difference in healing times between the two groups, so the researcher concluded that calcium intake has no effect on bone healing time. Why is the conclusion of the researcher not justified?
