question 33

Essay

Suppose you have used a randomized block design to compare the efficacy of three different doses of an experimental drug. You used seven patients in your study. The data are listed below. Do the data indicate that a particular dosage is more effective than other dosages? Apply the Friedman Fr-test to the data. Be sure to specify the null and alternative
hypotheses. Use $\alpha = 0.10$

$\quad$$\quad$$\quad$$\quad$$\quad$ $\text { Dosage }$
$\begin{array} { c c c c } \hline \text { Patient } & \mathrm { A } & \mathrm { B } & \mathrm { C } \\\hline 1 & 31 & 33 & 40 \\2 & 35 & 35 & 35 \\3 & 33 & 34 & 34 \\4 & 32 & 37 & 38 \\5 & 31 & 30 & 32 \\6 & 36 & 34 & 38 \\7 & 32 & 34 & 37 \\\hline\end{array}$
