question 19

Multiple Choice

The back-to-back stem-and-leaf display compares the percent growth in sales for a retail chain's stores located in two regions of Canada.The lower stem contains leaves with the digits 0-4 and the upper stem contains leaves with digits 5-9. $\begin{array} { r } \text{Region 1 Stores}\\\\\\\\211000 \\998876655555 \\444433\end{array}$ $\begin{array} { |l| } 6 \\6 \\5 \\5 \\4 \\4 \\3 \\3 \\2 \\2 \\1 \\1 \\0 \\0\end{array}$ $\begin{array} { l } \text{Region 2 Stores}\\5\\\\8\\\\\\\\556 \\34 \\67 \\233 \\55567 \\024444 \\56 \\444\end{array}$ Key: 3 $|~5$ = 35% sales growth

• A)The distribution of sales growth in Region 1 stores is unimodal,symmetric and tightly clustered around 35% growth.The distribution of sales growth in Region 2 stores is much more spread out,with most stores having sales growth between 5% and 35%.A typical Region 2 store had about 15% growth.There were two outliers,one store with 58% growth and another with 65% growth.Generally,the sales growth rates in the Region 2 stores were higher and more variable than the rates in the Region 1 stores.

Definitions:

Total Current

The complete or aggregate current flowing through a circuit, taking into account all phases and pathways.

Parallel Circuit

An electrical circuit where components are connected across common points or junctions, providing multiple paths for current.

Inductive Reactance

The resistance to the change in current flow by an inductor in an AC circuit, measured in ohms and dependent on frequency.

Inductive Reactance

Inductive reactance is the opposition to the change in current flow by an inductor, and it increases with an increase in the frequency of the applied electric signal.
