Seven Dwarfs
Several Years Ago a Television Station Interviewed Individuals

Short Answer

Seven Dwarfs
Several years ago a television station interviewed individuals and asked them to name the "Seven Dwarfs" from the story of "Snow White." The amount of time (in seconds)to name the dwarfs was recorded by age group.The data were: $$\begin{array} { | c | c | c | } \hline \text { Under 12 } & \text { 12 to 25 } & \text { Over 25 } \\\hline 60 & 120 & 75 \\45 & 65 & 45 \\38 & 60 & 75 \\30 & 48 & 55 \\35 & 150 & 100 \\\hline\end{array}$$
-The test question is: Do the different age groups require the same median time to name the Dwarfs? In testing the hypotheses,what is the appropriate critical value for the 0.05 significance level?
