Answer
There is sufficient evidence to reject that there is independence between the treatment and the fact that the patient stops smoking.
Work Step by Step
P=0.216. If the P-value is less than the significance level, then this means the rejection of the null hypothesis. Hence:P is more than $\alpha=0.1$, hence we reject the null hypothesis. Hence we can say that there is sufficient evidence to reject that there is independence between the treatment and the fact that the patient stops smoking.
