An experiment was conducted to compare the effectiveness of three "beta- blocker" medications on organizing heart-pumping rate for patients with Tachycardia. 18 patients were randomly selected, and after completion of the treatment prescription, the heartpumping rate (per minute) was measured for each patient. The records are in the following table: using Kruskal Wallis test with $\alpha =0.01$. The decision is: Don't reject ${\mathrm{H}}_0$. We reject $H_0$ because $\alpha =01$ is less than $\alpha =0.05$. We can't apply $\alpha =01$. Reject ${\mathrm{H}}_0$.
