Chapter 2: Q31. (page 106)

The circle graph at the right shows the results of a survey that asked, "How likely is it that you will be rich some day?" If the margin of error is $\pm 4 %$ what is the range of the percent of teens who say it is very likely that they will be rich?

Short Answer

Expert verified

The range is $11 %$ to $19%$ .

Step by step solution

Step-1. Construct the given pie chart.

The given pie chart is shown below in which margin of error is $\pm 4 %$

Step-2. Considering range of percentage of teens.

Let the range of percentage of teens who say that it is very likely that they will become rich be x.

Step-3. Evaluate range of percentage of teens.

This range of percentage of such teens can be calculated as:

$\begin{array}{l} x = 15 % (fromthepie-chart) \pm 4%(marginoferror) \\ x= (15 % - 4 %) to (15 % + 4 %) \\ x = 11 % to19% \end{array}$

Therefore, the range of percentage of teens who say that it is very likely that they will be rich is $11 %$ to $19%$ .
