Q 2.3. - The Practice of Statistics for AP

Question

Use the back-to-back stem plot in Figure $1.15$ to write a few sentences comparing the number of pairs of shoes owned by males and females. Be sure to address shape, center, spread, and outliers. 

Ignoring the outlier, the shape of the distribution is,

(a) skewed to the right and (c) skewed to the left. (e) skewed to the middle.

(b) roughly symmetric (d) bimodal.

Step-by-Step Solution

Answer

The correct option is (c) Curve is skewed to the left.

Step 1: Given Information

The stem pot is 

Step 2: Concept

An outlier is a value that is notably different from other values in a random sampling of the population.

Step 3: Explanation

This shows that residents aged $65$ and up are the most common. If Alaska is ignored, stem and leaf numbers will range from $9$ to $17$ The stem and leaf of the need are practically symmetrical. There isn't a single outlier. More values are to the left of the highest point than to the right. As a result, the curve is negatively skewed to the left.
