Chapter 1.2, Problem 62E

(a)

To determine

To compute:

Answer to Problem 62E

The smallest amount spent by any of shoppers is 3.

Explanation of Solution

Given:

As per the given stem-plot,

The key of plot is:

  $\text{Key: }9|3=\$92.50\text{ to \$93}\text{.49 spent}$

Calculation:

There are the following steps to compute the smallest amount spent by of the shoppers.

• Find the lowest value of left side in stem-plot
• Find the lowest value in corresponding to that left lowest value.

That is $0|3$ . Therefore, it can be converted through the key as:

  $0|3=\$2.50\text{ to \$3}\text{.49}$ . Thus, the nearest dollar is 3.

(b)

To determine

To find:The shape of distribution of amount spent by these 50 shoppers.

Explanation of Solution

Given:

As per given step-plot,

The left-tailed can be defined as the given below:

  

Since, the stem-plot is similar as the above.

Hence, the distribution of amount spent by these 50 shoppers, is left skewed.
