QuestionFind the 1st, 2nd, and 3rd quartiles of the hourly earnings data: $Q_{1}=$, $Q_{2}=$, $Q_{3}=$.

Studdy Solution
Calculate the value of the third quartile (Q3).
$$Q_{3} = \frac{17.55 +17.70}{2} =17.625$$So, the first, second, and third quartiles of the data set are$$\begin{array}{l} Q_{}=15.125 \\ Q_{2}=15.80 \\ Q_{3}=17.625\end{array}$$
