Answer 1

To find:

Which of these groups of relative frequencies would be best represented by a

pie chart?

A. 16%; 18%; 17%; 16%; 17%; 16%

B. 25%; 24%; 26%; 25%

C. 20%; 19%; 21%; 20%; 20%

D. 73%; 18%; 9%.

Explanation:

From the given data,

Consider B) 25%; 24%; 26%; 25%

Then,

$\begin{gathered} 25\%=\frac{25}{100} \\ =\frac{1}{4} \end{gathered}$

That implies,

$\frac{1}{4}\times360\degree=90\degree$

Since 24% approach 25% and 26% approach 25%.

Hence, option B) 25%; 24%; 26%; 25% is best to be represented by a piechart.
