The null hypothesis for this study would be that the medication has no effect on curing the common cold, and the alternative hypothesis would be that the medication is effective in curing the common cold. Based on the results shown in the table, the group that received the medication had a significantly higher percentage of patients who reported being cured of the common cold compared to the group that received sugar pills. Therefore, we would reject the null hypothesis and conclude that the medication was effective in curing the common cold.
