Q. 2.121 - Elementary Statistics

Question

In the special report "Mousetrap: The Most-Visited Shoe and Apparel E-tailers" (Footwear News, Vol. 58 , No. 3, p. 18), we found the following data on the average time, in minutes, spent per user per month from January to June of one year for a sample of $15$ shoe and apparel retail websites.

The following Minitab output shows a stem-and-leaf diagram for these data. The second column gives the stems, and the third column gives the leaves.

Step-by-Step Solution

Answer

Since the stem and lead diagram contains $5$ and not $6$ . This means the truncation was used.

Step 1: Given Information

A following Minitab output shows a stem-and-leaf diagram for these data. The second column gives the stems, and the third column gives the leaves. 

Step 2: Explanation

The supplied stem and leaf diagram display has $105$ on the first line.

This indicates that there is a single observation in the line between stem $0$ and leaf $5$, implying that the smallest value in the stem and leaf diagram is $05$ or simply $5$.

The set's smallest data value is $5.8$. Rounding $5.8$ to the nearest integer resulted in $6$, whereas truncation resulted in $5$.
