We cannot see the exact values of the test statistic and the degrees of freedom in Exhibit 12-3, but we do know that the p-value is less than .005. This means that there is strong evidence to suggest that the medication was effective in curing the common cold, and that the probability of observing these results by chance alone is less than .005.
